Aquantitative comparison is made between the absolute cross sections associated with statistical and dynamical emission of heavy fragments in the Sn-124 + Ni-64 and Sn-112 + Ni-58 collisions experimentally investigated at 35A MeV beam energy using the multidetector CHIMERA. The result shows that the dynamical process is about twice as probable in the neutron-rich Sn-124 + Ni-64 system as in the Sn-112 + Ni-58 neutron-poor one. This unexpected and significant difference indicates that the reaction mechanism is strongly dependent on the entrance-channel isospin (N/Z) content.
