Abstract
Charge symmetry and independence represent two of the fundamental properties of the nuclear interaction. The observation of charge symmetry-breaking effects has been long questioned, with a large experimental effort. The study of mirror energy differences represents a powerful tool able to highlight the occurrence and evolution of such phenomena in the nuclear matter as a function of the angular momenta. At the same time, the observation of exotic phenomena as super deformation and shape transitions and their dependency on neutron-proton pairing effects and isospin symmetry, have been pursued. The high-spin states in the light-mass Zinc isotopes revealed to be an excellent playground for the study of such phenomena. This work reports on two in-beam gamma-ray spectroscopic studies, aiming to investigate the nuclear structure by the observation of such effects. The first gamma-ray spectroscopy of the 55Cu nucleus extends the mirror energy difference studies beyond the proton drip line, where charge symmetry-breaking effects are expected to be enhanced. Simultaneously, a fusion-evaporation reaction populating the 63Zn isotope is presented, with the aim of extending the level scheme of this nucleus to higher angular momenta.File | Dimensione | Formato | |
