The ISOLDE Radioactive Beam Facility is the CERN experiment for the production and acceleration of radioactive nuclei. It is dedicated to the production, study and research of nuclei far from stability. Exotic nuclei of most chemical elements are available for the study of nuclear structure, nuclear astrophysics, fundamental symmetries and atomic physics, as well as for applications in...

Beta-delayed neutron emission βn is the dominant decay mode of the most exotic nuclei produced along the path of the rapid neutron capture process. The correct description of the final relative abundances of heavy elements requires a accurate knowledge of delayed neutron emission probabilities Pxn of very neutron-rich nuclei [1]. Our current understanding of this nuclear decay mode lacks of...

El fenómeno de clúster es bastante conocido en física nuclear, de hecho, algunas propiedades de los núcleos pueden describirse asumiendo únicamente algunas interacciones débiles entre dichos clústeres. Dentro de los núcleos ricos en neutrones, los clusteres pueden ser no sólo partículas estables, como la partícula alfa, sino también núcleos deformados y fácilmente polarizables. Este tipo de...

During the last two decades there has been a substantial effort directed to gather information about the region around the neutron-rich 132Sn [1], the most exotic doubly-magic nucleus presently at reach. Nuclei with a large N/Z ratio in this area of the table of isotopes are of great interest to test nuclear models and provide information about single particle states. Stringent tests of the...

Quasi-Free Scattering (QFS) reactions are powerful tool to study to provide information on nuclear single-particle properties. This experimental approach has been extensive in the past to gain information on stable nuclei [1] We have recently extended the method to explore the exotic species. The oxygen isotopic chain brings excellent opportunities covering a very broad range on isospin,...

A complete description of the fission process still represents a challenge, despite the recent progress based on time-dependent Hartree-Fock models [1]. Statistical models provide a tool to describe fission probabilities at excitation energies around the fission barrier. This approach is justified because, under such conditions, statistical times dominate over the typical timescales for the...

Traditionally effective interactions like Skyrme, Gogny or relativistic interactions have been used in basic mean field
approaches to describe with great success bulk properties
of ground states of nuclei, such as masses, quadrupole moments, radii, etc. However, recent developments in beyond
mean field calculations, with particle number and angular momentum projection in conjunction with...

There has been recent interest in low energy, high luminosity polarized electron beams for studies of parity-violating electron scattering, such as the MESA accelerator at Mainz or an upgraded FEL facility at Jefferson Lab. Accurate measurements of the parity-violating asymmetry in elastic electron scattering from nuclei can be used to determine Standard Model couplings, such as the...

Pairing correlations in nuclei is one of the most active fields in Nuclear Physics. It is crucial for understanding different processes and characteristics of nuclei such us superfluidity. We can easily found clear situations where neutrons form strongly correlated pairs with total angular momentum J=0 and isospin T=1. This produces a strong enhancement of two-neutron transfer reactions, thus...

An accurate determination of the core-crust transition is necessary in the modelling of neutron stars for astrophysical purposes. The properties of the transition are intimately related to the isospin dependence of the nuclear forces at low baryon densities.
Finite-range Gogny nuclear interactions are widely used in nuclear structure calculations but there are fewer studies of neutron stars...

En este trabajo se analiza el espectro del núcleo de 208Pb usando los datos experimentales recientemente obtenidos por Heusler et al. en el Maier-Leibnitz Laboratorium de Garching (Alemania). Han sido identificados los 151 estados más bajos y esto constituye el mayor conjunto de datos experimentales de estados ligados de un núcleo disponible a día de hoy para un estudio estadístico del caos...

Nucleon removal (p,pn) and (p,2p) reactions at intermediate energies have gained renewed attention in recent years as a tool to extract information from exotic nuclei, thanks to the availability of exotic beams with which to perform these reactions in inverse kinematics. These reactions explore the single-particle structure of the projectile nucleus and are complementary to nucleon removal...

Nucleons are not point like particles, they are made of quarks interacting each other by exchanging gluons. Gluons can be converted into quark-antiquark pairs giving raise to the sea quark. Quantum Chromodynamics (QCD) is the fundamental theory that describes the strong interaction; however, due to the complexity of the quark-gluon dynamics, QCD does not allow us to get analytical results in...

The development of high power laser systems based on the Chirped Pulse Amplification (CPA) technique [1] has lead to the advancement of the so called laser driven plasma accelerators. By focusing an ultra-intense ultra-short laser pulse in a target material, it is possible to produce accelerating gradients above 10 GeV/m, which are some 3 to 4 orders of magnitude larger than the values reached...
