The nuclear structure of 51Ar, an uncharted territory so far, was studied by the (p,2p) reaction using γ-ray spectroscopy for the bound states and the invariant mass method for the unbound states. Two peaks were detected in the γ-ray spectrum and six peaks were observed in the 50Ar + n relative energy spectrum. Comparing the results to our shell-model calculations, two bound and six unbound...
Reactions induced by alpha particles are important in multiple research areas such as nuclear astrophysics, nuclear technologies,dark matter searches and neutrino physics. Accurate data on neutron yields from the interaction of α-particles with nuclei via (α, n) reactions are of particular interest in this context. Despite the existence of experimental data and libraries, they show large...
Recently we have analysed two types of excited states generated from a ground state described by a pair condensate [1].
One type is obtained by breaking a pair from the ground state condensate and replacing it by ”excited” collective pairs built on time-reversed single-particle orbits. The second type is described by a condensate of identical excited pairs. The structure of these excited...
The study of beta decay of neutron rich nuclei is particularly important for many fields in fundamental and applied physics[1]. In nuclear reactors, fission products, through their decays, produce an additional power called decay heat[5]. The assesment of this energy is essential for nuclear safety since it represents around 7% of the power in an operating reactor and these decays continue...
Several works focused on light isotopes [1,2,3] have shown a reduction of the cross sections with respect to the theoretical predictions for single-nucleon knockout reactions. These studies have reached different conclusions regarding the dependence of the reduction factor observed of the spectroscopic factor with respect to the N/Z of the projectile. The study of (p,pX) knockout reactions...
The term "halo nucleus" was coined to describe nuclei exhibiting an unusually large spatial extension, deviating from the standard formula r=r$_o$⋅A$^{1/3}$. The initial empirical observation of this phenomenon arose from scattering experiments involving, among others, lithium isotopes [1]. These experiments, designed to measure the interaction cross-section of neutron-rich nuclei, revealed a...
The experimental data from quasielastic electron and (anti)neutrino scattering on $^{12}$C are reanalyzed in terms of a new scaling variable $\psi^*$ suggested by the interacting relativistic Fermi gas with scalar and vector interactions, which is known to generate a relativistic effective mass for the interacting nucleons. We construct a new scaling function $f^\text{QE}(\psi^*)$ for the...
