Abstract:
We shall discuss new features of fragmentation dynamics at the transition from semicentral to semiperipheral heavy-ion collisions at two beam energies, 35 AMeV and 45 AMeV respectively. Our investigation is performed within a microscopic transport model, Stochastic Mean Field (SMF). We have analyzed various kinematic features resulting from the numerical simulations for the two systems, 124Sn+64Ni and 124Xe+64Zn,respectively, considered also experimentally by CHIMERA collaboration. By employing two different parameterizations with density of symmetry energy we explore the possible correlations between the time scales of the fragmentation mechanisms and the dynamics of isospin degree of freedom.
