Influence of the N/Z ratio on Disintegration Modes of Compound Nuclei

Abstract : Investigations into the role of the N/Z ratio on the decay modes of compound nuclei are presented. Characteristics of fragments with atomic number 6$\leq$Z$\leq$28 and light charged particles emitted in 78,82Kr+40Ca at 5.5 MeV/A reactions were measured at the GANIL facility using the 4$\pi$-INDRA array. Data are compatible with an emission process from a compound nucleus. Persistence of structure effects and emission before full separation of fission fragments are evidenced from elemental cross-sections and coincidence data between light charged particles and fragments. Data are discussed in the framework of the transition state model
