In the def ormed nuclei in the nobelium region this allows an identification and mapp ing of single particle orbitals closest to the top end of the nuclear char t.\n\nInitial in-beam measurements in the region focussed on γ-ray spectr oscopy of even-even nuclei (e.g. 252\,254No\, 250Fm)\, studying the ground -state yrast bands and allowing extraction of parameters such as the momen ts of inertia\, and proving the deformed nature of these nuclei. More rece ntly\, attention has switched to odd-mass nuclei such as 253No\, 251Md and 255Lr\, the latter being the heaviest nucleus so far studied in-beam. Rot ational bands have been observed in all these nuclei. Non-yrast and K-isom eric states have recently been observed in 252\,254No and 250Fm through th e use of both in-beam and focal plane decay spectroscopy. The studies empl oyed a calorimetric technique\, whereby the summed energy from a cascade o f conversion electrons is detected in a DSSSD detector and used as a “ta g” for γ-rays detected in the various germanium detectors. These experi ments have yielded data which can be used to determine the excitation ener gies and configurations of two-quasiparticle states in the region\, and co mpared to the predictions of various theories. These comparisons show that reasonable agreement is obtained with Woods-Saxon approaches but discrepa ncies are observed with the predictions of HFB calculations with SLy4 or G ogny interactions. Such observations highlight the need for such detailed spectroscopic data in order to improve the interactions used in these mode rn approaches.\n\nAn overview of the most recent results and the experimen tal techniques used will be presented and new experimental developments su ch as the SAGE spectrometer coming online in Jyväskylä and the new TASIS pec setup at will be discussed.\n\n\n* This work is supported by the UK ST FC.\n\n[1] R-D Herzberg\, J.

The project\, since 1998 named MYRRHA\, has evolved to a larger ins tallation\, able to work in subcritical mode (as an Accelerator Driven Sys tem) and in critical mode.\n\nApart from the experimental and irradiation possibilities in the subcritical reactor\, the MYRRHA proton accelerator o n its own can be used as a supply of proton beams for a number of experime nts. In order to explore new research opportunities offered by the acceler ator\, a pre-study was carried out within the framework of the “Belgian Research Initiative on eXotic nuclei” (BriX) network of the Interunivers ity Attraction Poles Programme of the Belgian State. This study was invest igating unique possibilities for fundamental research using high-intensity proton beams with a fraction of the full beam during ADS operation (up to 200 µA). \n\nAn interesting approach for fundamental research using the 600-MeV proton accelerator is the installation of an Isotope Separator On- Line (ISOL@MYRRHA) facility with a ruggedized target-ion source system\, w hich is able to provide intense low-energy Radioactive Ion Beams (RIB) for experiments requiring very long beam times (up to several months). This o pens unique opportunities for RIB research in various scientific fields\, which is complementary with the activities at other existing and future fa cilities. \n\nMYRRHA is foreseen to be in full operation by 2024 and it wi ll be operated in the first years as an ADS. In a second phase\, when the MYRRHA reactor will run as a stand-alone critical reactor\, the full proto n-beam intensity might be used for ISOL@MYRRHA or other applications.\n\nT his presentation will introduce the MYRRHA and ISOL@MYRRHA facilities\, th e physics that can be uniquely addressed at ISOL@MYRRHA\, the present stat us of the project and future plans.\n\nhttps://indico.ific.uv.es/event/349 /contributions/6173/ LOCATION:Colegio Rector Peset URL:https://indico.ific.uv.es/event/349/contributions/6173/ END:VEVENT BEGIN:VEVENT SUMMARY:Spectroscopy of N~Z Nuclei: 100Sn and Neighbours DTSTART;VALUE=DATE-TIME:20110222T140000Z DTEND;VALUE=DATE-TIME:20110222T144000Z DTSTAMP;VALUE=DATE-TIME:20260514T192847Z UID:indico-contribution-349-6172@indico.ific.uv.es DESCRIPTION:Speakers: Thomas Faestermann (Physics Dept.\, T U München)\nW e have produced 100Sn and nuclei in its neighbourhood by fragmentation of 124Xe ions from the SIS at GSI\, Darmstadt. The fragments of interest were separated and identified in the FRS. In addition to 259 nuclei of 100Sn w e observed for the first time the N=Z-1 nuclei 93Ag\, 95Cd\, 97In and 99Sn . Because of the reduced yield of 103Sb we conclude that proton radioacti vity with a half life below 100ns is its dominant decay channel. The fragm ents were stopped in a stack of DSSDs for the correlation of implantation with subsequent decays. Ten Si detectors in front and behind this implanta tion zone served as calorimeter for betas. The implantation detector was s urrounded by the 105 Ge detectors of the RISING array. A number of isomeri c states was observed. In 102Sn we find a new isomeric gamma-line which we attribute to the 6+-4+ transition. In 98Cd we also observe an unknown tra nsition\, shedding light on core excited states. For the decay of 100Sn we deduce a precise value of the half-life and of the decay energy to the lo west 1+ state in 100In. That gives us the GT strength of the decay which is the largest ever seen. For the first time we observe the gamma-cascade depopulating that 1+ state. It appears that the description of 100Sn and 1 00In in the truncated model space for protons (p1/2\, g9/2) and neutrons ( d5/2\, g7/2\, d3/2\, s1/2\, h11/2) works remarkably well.\n\nhttps://indic o.ific.uv.es/event/349/contributions/6172/ LOCATION:Colegio Rector Peset URL:https://indico.ific.uv.es/event/349/contributions/6172/ END:VEVENT BEGIN:VEVENT SUMMARY:Studies in the 100Sn region with radioactive Beams DTSTART;VALUE=DATE-TIME:20110222T144000Z DTEND;VALUE=DATE-TIME:20110222T152000Z DTSTAMP;VALUE=DATE-TIME:20260514T192847Z UID:indico-contribution-349-6171@indico.ific.uv.es DESCRIPTION:Speakers: Joakim Cederkall (Lund University)\nThe higher inten sities at EURISOL will make several new isotopes in the 100sn region avail able for studies.

These so-called superallowed beta decays provide the most p recise value of V_ud\, the up-down element of the Cabibbo-Kobayashi-Maskaw a (CKM) quark-mixing matrix. The most stringent test of the CKM matrix is the top-row unitarity test\, where V_ud contributes the most. Currently th ere are 13 superallowed transitions ranging from 10C to 74Rb that are dete rmined accurately enough to contribute to the world average.\n\nThe three experimental quantities that are required to extract V_ud from a superallo wed decay are the branching ratio (BR) of the superallowed 0+ to 0+ transi tion\, the half-life (T_1/2) of the parent state and the decay energy (Q_E C). Additionally\, a few theoretical correction terms are needed.\n\nThe J YFLTRAP Penning-trap setup at the University of Jyväskylä\, Finland\, ha s contributed to these studies mainly with high-precision Q-values. Since 2006\, Q values of 15 different superallowed transitions\, ranging from 10 C to 62Ga\, have been determined with high precision. Since JYFLTRAP is co upled to the IGISOL mass separator\, any element is available. Simultaneus production enabled us to determine a Q_EC value by measuring the frequenc y ratio of the parent and daughter ions directly. Using this so-called dou blet technique and utilizing state-of-the art methods\, such as ion-motion excitation with time-separated oscillatory fields\, we have reached preci sions down to the 50-eV level.\n\nIn this contribution\, the results and i mpact of the Q-value measurement program at JYFLTRAP will be presented.\n\ nhttps://indico.ific.uv.es/event/349/contributions/6166/ LOCATION:Colegio Rector Peset URL:https://indico.ific.uv.es/event/349/contributions/6166/ END:VEVENT BEGIN:VEVENT SUMMARY:Rp-process DTSTART;VALUE=DATE-TIME:20110222T080000Z DTEND;VALUE=DATE-TIME:20110222T084000Z DTSTAMP;VALUE=DATE-TIME:20260514T192847Z UID:indico-contribution-349-6165@indico.ific.uv.es DESCRIPTION:Speakers: Fernando Montes (NSCL)\nhttps://indico.ific.uv.es/ev ent/349/contributions/6165/ LOCATION:Colegio Rector Peset URL:https://indico.ific.uv.es/event/349/contributions/6165/ END:VEVENT BEGIN:VEVENT SUMMARY:Gamow-Teller Resonances in the beta decay and Charge-Exchange Reac tions DTSTART;VALUE=DATE-TIME:20110221T144000Z DTEND;VALUE=DATE-TIME:20110221T152000Z DTSTAMP;VALUE=DATE-TIME:20260514T192847Z UID:indico-contribution-349-6164@indico.ific.uv.es DESCRIPTION:Speakers: Yoshitaka Fujita (Department of Physics\, Osaka Univ ersity)\nGamow-Teller (GT) transitions are caused by the most common weak interaction of spin-isospin (στ) type with ΔL = 0. Since spin and isos pin are unique quantum numbers in nuclei\, GT transitions represent very i mportant nuclear response. GT transitions are studied by the β decay and charge-exchange (CE) reactions. The β decay has a direct access to the ab solute GT transition strengths B(GT) from a study of half-lives\, Q-values and branching ratios\, but it can only access states at excitation energi es lower than the decay Q-value. In contrast\, the CE reactions\, e.g. (3H e\,t) reaction\, at intermediate beam energies and 0º\, can selectively e xcite GT states up to high excitation energies in the final nucleus. \n Although the study of GT strength in the β decay is restricted by the dec ay Q-value\, unstable nuclei can have the Q-value of 12 MeV or larger\, wh ich\, in principle allows the study of the central part of the GTR where t he GT strength is concentrated. Possibility of observing GTR structures in β-decay studies will be discussed on the basis of the GTR studies by (3H e\,t) reactions assuming a good isospin symmetry of nuclear structure and transitions.\n\nhttps://indico.ific.uv.es/event/349/contributions/6164/ LOCATION:Colegio Rector Peset URL:https://indico.ific.uv.es/event/349/contributions/6164/ END:VEVENT BEGIN:VEVENT SUMMARY:Superallowed Fermi decays: precise T1/2 and branching ratios measu rements DTSTART;VALUE=DATE-TIME:20110221T152000Z DTEND;VALUE=DATE-TIME:20110221T160000Z DTSTAMP;VALUE=DATE-TIME:20260514T192847Z UID:indico-contribution-349-6163@indico.ific.uv.es DESCRIPTION:Speakers: Jérôme Giovinazzo (CENBG / IN2P3 / CNRS)\nThrough the studies of Fermi transitions between 0+ analog states with T = 1 (su perallowed transitions)\, nuclear physics provides a valuable test of the Standard Model of particle physics. These transitions depend only on the v ector part of the weak interaction\, and according to the conserved vector current (CVC) hypothesis\, their strength Ft is a constant. Then this val ue is used to determine the Vud term in the CKM quark mixing matrix\, that should be unitary.\nThe constant Ft strength determination requires very high precision measurement of the decay energy QEC (related to masses) and of the partial half-life of the transition (parent nucleus half-life T1/2 and branching ratio BR)\, but it also requires some theoretical correctio ns of the experimental values. Then\, beside the search for “new physics ” if deviations from the standard model are observed\, such studies are a very sensitive test of the theoretical descriptions used to calculate th ose corrections.\nIn this presentation\, I will give a general view of the landscape of nuclei of interest for those studies\, with a focus on recen t experimental results concerning the T1/2 and BR measurements that we per formed at Jyväskylä university and ISOLDE at CERN : 26Si\, 30S\, 42Ti\, 38Ca and 62Ga. These results have to be compared with other measurements t hat have been performed worldwide\, showing the strong activity in this fi eld. Finally\, expectations and limitations for further studies will be ad dressed.\n\nhttps://indico.ific.uv.es/event/349/contributions/6163/ LOCATION:Colegio Rector Peset URL:https://indico.ific.uv.es/event/349/contributions/6163/ END:VEVENT BEGIN:VEVENT SUMMARY:New Vistas in Experimental Searches for Proton Radioactivity DTSTART;VALUE=DATE-TIME:20110221T112000Z DTEND;VALUE=DATE-TIME:20110221T120000Z DTSTAMP;VALUE=DATE-TIME:20260514T192847Z UID:indico-contribution-349-6162@indico.ific.uv.es DESCRIPTION:Speakers: Philip J. Woods (University of Edinburgh)\nThe talk will consider where we currently stand in terms of the exploration of one proton radioactivity. Proton radioactivity provides a uniquely sensitive p robe of nuclear shape and shell structure beyond the proton drip-line. Thi s varied nuclear landscape in turn provides us with a laboratory in which to explore the dramatic influence of shape and shell structure on the pro ton quantum tunneling probability. The talk will explore new experimental approaches to the study of this fascinating phenomenon\, including the exp loration of new regions of the proton-drip-line\, and regions of shape co- existence\, where shape effects on tunneling would be probed in a uniquely sensitive manner.\n\nhttps://indico.ific.uv.es/event/349/contributions/61 62/ LOCATION:Colegio Rector Peset URL:https://indico.ific.uv.es/event/349/contributions/6162/ END:VEVENT BEGIN:VEVENT SUMMARY:Spectroscopy studies of N≈Z nuclei DTSTART;VALUE=DATE-TIME:20110221T140000Z DTEND;VALUE=DATE-TIME:20110221T144000Z DTSTAMP;VALUE=DATE-TIME:20260514T192847Z UID:indico-contribution-349-6161@indico.ific.uv.es DESCRIPTION:Speakers: J.J. Valiente Dobon (LNL-INFN)\nThe properties and s tructure of nuclei with equal number of protons and neutrons have been in the last decades an intense field of research\, both experimentally and t heoretically. The structure of these nuclei provide essential infomation\, among other things\, about the isospin symmetry of the nuclear force as w ell as on proton-neutron correlations. As an example\, the isobaric analog ue states in mirror nuclei have shed light on the presence of isospin non- conserving forces in nuclear matter. From the detailed studies of energy d ifferences between those states\, an important theoretical understanding o f the nuclear force in the f p shell [1]\, has been achieved\, recently ex tended to include the g9/2 [2\, 3]. Furthermore\, N = Z nuclei present enh anced correlations between neutrons and protons that occupy orbitals with the same quantum numbers. For heavier N = Z nuclei the T = 0 isoscalar cor relations become more relevant than the usual T = 1 isovector pairing\, gi ving rise to an unusual type of nuclear superfluidity [4].\n Spectrosc opy of excited states of these neutron-deficient nuclei has been demonstr ated to be a powerful tool to understand in detail the nature of the nucle ar force. This has been possible thanks to the advent\, in the last decade s\, of large γ -ray arrays with the associated complementary detectors th at allowed to access these very exotic N≈Z nuclei at high spins. Future studies of the exotic neutron-deficient nuclei will mainly require the us e of reactions induced by intense radioactive heavy-ion beams as those pro vided by near-future facilities and in the future by Eurisol. This will al low an unprecedented study of the heaviest N = Z nuclei located even furth er from the line of beta stability. In this presentation\, the isospin sym metry\nand the proton-neutron correlations will be discussed with special attention to the perspectives offered by the new radioactive-ion beam faci lities.\n 1.

Borge (Instituto de Estructura de la Materia\, CSIC)\nThe beta decay process allows for understanding the inter actions and behaviour of the nucleons inside the nucleus. The process is w ell understood and the interpretation of the data yields a wide variety of spectroscopic information: level energies\, spins\, parities\, widths and level densities.\n\nOften the key nuclei to understand how such a complex system can be constructed from a few ingredients are very neutron or very proton rich. Such exotic systems allow isolating and amplifying specific aspects of the nucleonic interactions\, and uniquely display the physics o f loosely bound systems governed by the strong interaction. Beta decay can also shed light on some fundamentals of the weak interaction\, which it i s the main contributor to the process.\n\nGoing far from stability the dif ference in isobaric masses increases quadratically and the binding energy of the last nucleon decreases dramatically\, the beta-delayed particle emi ssion becomes dominant near the drip lines. The beta transitions feed unbo und excited states and they are followed by delayed particle emission. The high efficiency for the charged particle detection makes the study of the beta delayed particles a unique tool to understand the nuclear structure of very rare species through very exotic decay modes.\n\nIn this contribut ion recent achievements in particle decay studies will be presented. The d ifferent techniques developed to do high quality spectroscopy of very low produced exotic nuclei\, will be revised.\n\nhttps://indico.ific.uv.es/eve nt/349/contributions/6157/ LOCATION:Colegio Rector Peset URL:https://indico.ific.uv.es/event/349/contributions/6157/ END:VEVENT BEGIN:VEVENT SUMMARY:In-gas cell laser spectroscopy of neutron-deficient silver isotope s DTSTART;VALUE=DATE-TIME:20110221T171000Z DTEND;VALUE=DATE-TIME:20110221T173500Z DTSTAMP;VALUE=DATE-TIME:20260514T192847Z UID:indico-contribution-349-6156@indico.ific.uv.es DESCRIPTION:Speakers: Piet Van Duppen (Instituut voor Kern- en Stralingsfy sica)\nIn-gas cell laser spectroscopy has been developed at the Leuven Iso tope Separator On-Line\n(LISOL) set-up using heavy- and light-ion induced reactions.

Jenkins (York University)\nA remarkable feature o f the atomic nucleus is its ability to take on different mean-field shapes for a small cost in energy. Since this phenomenon is a strong challenge t o state-of-the-art theory\, experimental data can provide a discriminating test of competing models. A strong focus for explorations of nuclear shap e coexistence in recent years has been the region around the light lead nu clei. Both prolate and oblate shape minima are found to compete favourably with the spherical ground state. The prolate minimum reaches its lowest e nergy around the neutron mid-shell (N=104) and this trend has has been rec ently confirmed with the observation for the first time of excited states in the extremely exotic nucleus\, 180Pb. These results will be presented.\ nIncreasingly\, the focus has shifted to measurement of matrix elements wh ich can impose even more stringent tests of nuclear models. Very recently\ , the scope for extracting matrix elements has been opened up at REX-ISOLD E where accelerated ISOL beams of very heavy proton-rich nuclei are unique ly available. Coulomb excitation can be used to extract both transition an d diagonal matrix elements\; the latter giving information on the sign of the nuclear deformation. Recent results on Coulomb excitation of the light mercury and radon will be presented. This work has been complemented with experiments to obtain independent information on transition matrix elemen ts using plunger lifetime measurements. Studies of excited states in the l ight radon and mercury nuclei have also been carried out using the novel S AGE spectrometer at the University of Jyvaskyla\, where conversion electro ns can be detected in coincidence with gamma rays. This approach can be us ed to search for E0 transitions and E0 components of J-J transitions which are an important further insight into shape coexistence in these nuclei. Preliminary data from both the plunger and SAGE measurements will be prese nted. \nIn the future\, the HIE-ISOLDE facility at CERN will provide accel erated beams of heavy neutron-deficient nuclei up to 10 MeV/u. This will a llow multi-step Coulomb excitation as well as the opportunity to probe the shape coexistence in still further detail by means of transfer reactions. An outline of these possibilities will be given. \nThe work to be present ed represents the contribution of many individuals and groups from the MIN IBALL/REX-ISOLDE collaboration and the SAGE/JYFL collaboration.\n\nhttps:/ /indico.ific.uv.es/event/349/contributions/6152/ LOCATION:Colegio Rector Peset URL:https://indico.ific.uv.es/event/349/contributions/6152/ END:VEVENT BEGIN:VEVENT SUMMARY:Symmetries in proton-rich nuclei seen through ground-state propert ies DTSTART;VALUE=DATE-TIME:20110222T174500Z DTEND;VALUE=DATE-TIME:20110222T181000Z DTSTAMP;VALUE=DATE-TIME:20260514T192847Z UID:indico-contribution-349-6151@indico.ific.uv.es DESCRIPTION:Speakers: Magdalena Kowalska (CERN)\nLight proton-rich nuclei are valuable objects to study various symmetries in nuclear systems: funda mental symmetries with superallowed decays\, proton-neutron isospin symmet ry\, or shapes\, i.e. the geometrical symmetry.\nGround-state property mea surements\, such as these performed at ISOLDE with laser spectroscopy and Penning-trap mass spectrometry\, contribute to this topic. In this contri bution I will present recent investigations using the COLLAPS and ISOLTRAP setups which cover masses\, moments\, and charge radii of proton-rich Ne\ , Mg\, and K isotopes. \nSymmetries are addressed in multiple ways: Magnet ic moments of 21Mg and 17Ne allow studying the isospin symmetry. Charge ra dii of both isotopic chains reveal a wealth of geometrical phenomena\, fro m proton halos to alpha-clustering\, when adding only a few neutrons. The mass of 35K gives evidence for a breakdown of the isobaric multiplet mass equation and the precise mass of 22Mg contributes to the determination of the Vud matrix element.\n\nhttps://indico.ific.uv.es/event/349/contributio ns/6151/ LOCATION:Colegio Rector Peset URL:https://indico.ific.uv.es/event/349/contributions/6151/ END:VEVENT BEGIN:VEVENT SUMMARY:The FARCOS Project - A Femtoscope ARray for COrrelations and Spect roscopy DTSTART;VALUE=DATE-TIME:20110222T172000Z DTEND;VALUE=DATE-TIME:20110222T174500Z DTSTAMP;VALUE=DATE-TIME:20260514T192847Z UID:indico-contribution-349-6150@indico.ific.uv.es DESCRIPTION:Speakers: Giuseppe Verde (INFN\, Sezione di Catania)\nCorrelat ions between two or more particles emitted during a nuclear reaction provi de tools to study time properties of the reaction and can be used as well to explore spectroscopic properties of exotic clusters. With the aim of st udying two- and multi-particle correlation functions the FARCOS project (F emtoscope ARray for COrrelations and Spectroscopy) has been conceived as a n array of double sided silicon strip detectors and CsI(Tl) crystals chara cterized by high angular and energy resolution. The array will address top ics covering both nuclear dynamics and spectroscopy with stable and radioa ctive beams. \nThe array will address the study of correlation measurement s in nuclear dynamics with the use of high resolution imaging techniques p roviding sort of “space-time” snapshots of particle and complex fragme nts emitting sources. These “space-time images” will be shown to probe the N/Z degree of freedom in nuclear reactions\, providing important prob es of the sub-saturation density dependence of symmetry energy.\nIn the ve ry same collision events\, several exotic nuclear fragments are produced. Most of them are unbound and can be studied by means of two- and multi-par ticle coincidence measurements. These measurements reveal the existence of resonances and provide important spectroscopic information on the explore d unbound states such as their spin and their branching ratios with respec t to specific and new decay channels. \nThe high resolution that is planne d to be available with the Farcos array will allow performing important st udies of exotic decay channels by means of the complete reconstruction of their final momentum vectors. These studies can also provide important inf ormation about the formation and decay of special cluster states in stable and exotic nuclei. Examples of applications in the decay of unbound state s in 10C\, 12C and other light nuclei will be shown and the perspectives o ffered by Farcos will be stressed. \nAn important aspect of Farcos will be represented by its pulse-shaping capabilities that will allow the detecti on and identification of particles and fragments moving at low energies an d stopped in the first layer of the silicon strip detector. These pulse-sh ape techniques will be of fundamental importance in order to study particl e correlations even in low energy reactions. The electronics under develop ment will play a special attention to new technologies in generic and inte grated electronics. \nThe modularity of FARCOS will allow coupling it to o ther devices such as 4π detectors and magnetic spectrometers. The possibi lity of coupling to neutron detector arrays to perform high resolution pro ton-neutron correlation measurements is also under consideration. \nThe Fa rcos project aims at providing important perspectives for studies at the f uture European radioactive beams facilities such as Spiral2\, Spes and Eur isol\, both in the field of nuclear dynamics and spectroscopy.\n\nhttps:// indico.ific.uv.es/event/349/contributions/6150/ LOCATION:Colegio Rector Peset URL:https://indico.ific.uv.es/event/349/contributions/6150/ END:VEVENT BEGIN:VEVENT SUMMARY:Selective sensitivity of proton scattering to densities on the nu clear surface DTSTART;VALUE=DATE-TIME:20110222T165500Z DTEND;VALUE=DATE-TIME:20110222T172000Z DTSTAMP;VALUE=DATE-TIME:20260514T192847Z UID:indico-contribution-349-6149@indico.ific.uv.es DESCRIPTION:Speakers: Hugo Arellano (Physics Department - FCFM - U Chile)\ nMicroscopic descriptions of nucleon scattering from nuclei depend on the matter distribution of their neutron and proton constituents. Additionally \, the different behaviour of density-dependent effective\ninteractions in the pp and pn channels offer a selective mechanism by which proton probes couple to the proton and neutron densities of the nucleus. Recent formal studies of the optical model potential have\ndemonstrated the surface cont ributions to the optical potential depend on the gradient of the density-d ependent effective interaction\, and that proton probes couple strongly to the neutron than to the proton\ndensity. These properties poses limits th e sensitivity of proton scattering to the matter distribution of proton-ri ch nuclei.

Apart from displaying some rather interesting nuclear structure ef fects\, the\nsuperallowed 0+ → 0+ Fermi β decay of these nuclei is a va luable tool in probing many properties of the\nweak interaction. Nuclei at or near the N=Z line are of particular interest as micro-laboratory for h igh\nprecision tests of the Standard Model. The isospin symmetry breaking is also responsible for the mirror\nenergy differences induced by electrom agnetic and charge-dependent strong interactions. Anomalies have\nbeen exp erimentally identified in the excitation energy of the analog states in t he A≃70 mass region.\nThe properties of these nuclei are important for t he rp process and the understanding of the nucleosyn-\nthesis. The simulat ion of many astrophysical objects requires the knowledge of properties and decay rates\nof nuclei near the proton drip line. Relevant for the Gamow- Teller (GT) beta decay of the waiting point\nnuclei could be the GT streng th distributions for the low-lying excited states whose thermal population \nmay result in a significant reduction of the effective lifetime at the high temperatures of X-ray bursts.\nShape coexistence and mixing\, isospin mixing\, significant neutron-proton pairing correlations competing\nwith the like-nucleon ones\, and competition between proton and neutron alignm ent have been identified\nas the main characteristic features of nuclei n ear the N=Z line in the A≃70 mass region.

This observation is made in the context of the spherical shell model on the basis of several realistic two-nucleon interactions. Shell-model r esults are analyzed in terms of a variety of two-nucleon pairs correspondi ng to different choices of their coupled angular momentum J and isospin T. The analysis is performed exactly for four holes (96Cd) and carried furth er for six and eight holes (94Ag and 92Pd) by means of a mapping to an app ropriate version of the interacting boson model.\nOn the basis of these re sults one concludes that a realistic model can be formulated in terms of s (with J=0) and b (i.e.\, aligned J=9) bosons.

Of particular interest is the competition between isovector ( T=1) and isoscalar (T=0) Cooper pairs\, expected to occur in N=Z nuclei .\ n\nNear 40Ca and 56Ni\, earlier systematic analyses of two-neutron (L=0) t ransfer reactions [1\,2] found the data consistent with a picture involvin g configuration mixing induced by simple pairing degrees of freedom of the valence neutrons. While providing evidence for isovector pairing in the f orm of pairing vibrations [2\,3]\, the question of whether the isoscalar c omponent generates collective modes is still an open one.\n\nDirect reacti ons involving the transfer of an np pair from even-even to the low lying 0 +\,1+ states in odd-odd self conjugate nuclei could be excellent probes to study np correlations. While absolute cross-section values are always des irable\, we note that the ratio σ(0+)/σ(1+) itself provides an almost mo del independent measure of the pairing collectivity in the respective chan nels. Thus\, the (3He\,p) reaction stands out as an ideal tool to study np correlations.\n\nFollowing a short overview of the subject\, we will disc uss a series of experiments carried out at the Argonne ATLAS facility to s tudy the (3He\,p) reaction in reverse kinematics and present results obtai ned with a beam of 44Ti [4].\n\nWe will also speculate on the use of np kn ockout reactions and conclude by delineating a possible path as we move to wards the next generation of rare isotopes facilities. \n\n*Supported by T he U.S. DOE under contract DE-AC02-05CH11231\n1.
