Isospin influence on the decay modes of compound nuclei produced in the ^78,86 Kr+ ^40,48Ca at 10 MeV/nucleon

The study of the decay modes competition of the compound systems produced in the collisions ⁷⁸Kr+⁴⁰Ca and ⁸⁶Kr+⁴⁸Ca at 10MeV/A is presented. In particular, the N/Z entrance channel influence on the decay paths of the compound systems, directly connected to the isospin influence, is investigated. The experiment was performed at the INFN Laboratori Nazionali del Sud (LNS) in Catania by using the 4π multi-detector CHIMERA. Charge, mass, angular distributions and kinematical features of the reaction products were studied. The analysis shows some differences in the contribution arising from the various reaction mechanisms for the neutron-poor and neutron-rich systems.
