Description

The population and gamma-decay of n-rich nuclei around 48Ca was measured at LNL using deep-inelastic collisions (DIC) on 64Ni, at an energy ~2.5 times above the Coulomb barrier. The experimental setup consisted of the CLARA Ge array coupled to the PRISMA magnetic spectrometer. DIC are proved to be a powerful tool to study nuclear properties far from stability and a starting point for extracting nuclear structure information is the study of the reaction dynamics. In this contribution we present a detailed investigation of the reaction properties, such as total cross sections and energy integrated angular distributions of the most relevant transfer channels, taking into account a detailed study of the response of the PRISMA magnetic spectrometer. The experimental results are compared with predictions from the semiclassical multi-nucleon transfer model of ref. [1], which is found to well reproduce the data corresponding mainly to one nucleon transfer. For the first time with heavy ions, angular distributions of reaction channels leading to specific excited states have been measured, and the experimental results are interpreted in terms of DWBA calculations, providing structure information on B(E2)’s, spectroscopic factors and particle-vibration coupling. A similar analysis has also being performed in neutron rich Ne isotopes, giving further support to the importance of DIC in the study of basic nuclear structure properties also in connection with more exotic nuclei.
