Abstract

An investigation of the influence of the isospin (N/Z ratio) on the thermometric characteristics, in the reactions ⁷⁸Kr+⁴⁰Ca and ⁸⁶Kr+⁴⁸Ca at 10 AMeV is presented. The experiment was performed at the INFN Laboratori Nazionali del Sud in Catania by using the beams delivered by the Superconductive Cyclotron and the 4π multidetector CHIMERA. The isospin effects on the decay modes of the two produced composite systems and on the competition between statistical and dynamical break-up of the projectile have been studied. The thermal evaporation from both compound nucleus (CN) and Quasi-Projectile Like Fragment (PLF) has been investigated by extracting the temperature with two different thermometric methods, namely the slope thermometer, with the alpha particles as probe, and the double isotope yields ratio thermometer. The results of the analysis suggest the influence of the N/Z ratio on the system (CN or PLF) temperature, regardless of the nature of the method used for its determination.
