Low Energy Reaction Mechanisms In a Transport Approach

Abstract

Starting from Heavy Ion Collisions with exotic nuclear beams at low energy, the reaction path is investigated in a transport theory based on a stochastic mean field approach. We focus on the interplay between reaction mechanisms, fusion vs. break-up in HIC with exotic nuclear beams at low energies. Fusion probabilities for reactions induced by 132Sn on 64,58Ni targets at 10AMeV are evaluated looking at the evolution of the phase-space quadrupole collective modes. The break-up events appear sensitive to the stiffness of the symmetry energy. 197Au + 197Au collisions at 15 and 23 AMeV are simulated to investigate the main modes of re-separation, ternary-quaternary partition, of a heavy nuclear system.
