Abstract

The influence of the neutron richness on binary decays is investigated in 78,82Kr+40Ca reactions at 5.5 MeV/A incident energy. Kinetic energy distributions and angular distributions of fragments with atomic number 6≤Z≤28 were measured using the 4-INDRA array. Global features are compatible with an emission from a long-lived system. The yields around the symmetric splitting are about 30% smaller for the neutron rich system. The persistence of strong structural effects is evidenced from elemental cross-sections of the light fragments. The cross-sections for odd-Z fragments are higher for the neutron rich CN while cross-sections for even-Z fragments are higher for the neutron poor CN. Calculations assuming two different potential energy surfaces are presented.
