Description
Transfer reactions play an essential role in the understanding of collision dynamics and nuclear structure. Low energy multinucleon transfer reaction is one of the most important tool to probe nucleon-nucleon correlations in nuclear systems. The recent revival of transfer reaction studies
greatly benefited from the construction of the new generation instrumentations that reached an unprecedented efficiency and selectivity.
Transfer cross sections obtained from excitation functions for the closed shell 40Ca+96Zr and super fluid 60Ni+116Sn systems have been measured from the Coulomb barrier energy to energies corresponding to very large distances of closest approach where the nuclear absorption is negligible. We also performed a gamma-particle AGATA-PRISMA coincidence experiment for
the 60Ni+116Sn system in order to investigate the ground and excited state population of the two-neutron transfer channel. The experimental transfer probabilities have been compared with microscopic calculations that incorporate nucleon-nucleon correlations, essential for the population pattern of the single particle levels around the Fermi energy. These calculations very well reproduce the experimental data in the whole energy range. In particular, for the first time in a heavy ion collision, one- and two-neutron transfer channels have been very well reproduced in shape and magnitude.
