Abstract :

The structure of neutron-rich sdfp-shell nuclei at intermediate energies and spins $J\leq 8$ can be elucidated using deep-inelastic reactions. Such information is required as a test of state-of-the-art shell-model calculations. Using the magnetic spectrometer PRISMA coupled to the γ-ray array CLARA, multi-nucleon transfer reactions using a beam of 36S ions and a thin-target of 208Pb have been used to populate states in neutron-rich Si, P, S and Cl nuclei. The unambiguous γ-mass correlations obtained from the experimental data can be better understood when combined with deep-inelastic reactions using thick-targets in which γγγ correlations have been obtained. To this end, the results of the PRISMA/CLARA reaction will be discussed in parallel with those of two thick-target experiments conducted using GASP and Euroball. A comparison of experimental results and the results of shell-model calculations will also be presented. Personnes a contacter :
