Population and y-decay studies of neutron-rich nuclei around 48Ca with deep inelastic collisions

The population and -decay of n-rich nuclei around 48Ca has been measured with the PRISMA-CLARA setup using deep-inelastic collisions (DIC) on 64Ni, at energies ~2.5 times above the Coulomb barrier. After a careful analysis of the response of the PRISMA magnetic spectrometer, a detailed investigation of the reaction properties is carried out. This provides total cross sections and energy integrated angular distributions of the most relevant transfer channels, which are compared with predictions from a semiclassical multi-nucleon transfer model. Good agreement is found for the 0p, 1p and 1n channels. In few cases, angular distributions of the first excited states are also measured and the experimental results are interpreted in terms of DWBA calculations, providing information on the basic ingredients of the theoretical models.
