Abstract

In this work, the preliminary results of the data analysis on the influence of the isospin on the thermometric characteristics, in the reactions 78Kr+40Ca and 86Kr+48Ca at 10 AMeV, will be shown. The thermal evaporation from compound nucleus and from the Quasi-Projectile have been studied within the thermometric method, based on the kinematic approach, in which the temperatures are extracted from the slope of the alpha particles energy spectra. Moreover, the values of the temperature, in fusion reactions, were measured with two different helium isotope ratio thermometers. In fusion-reactions higher temperature has been found for the system with higher neutron enrichment, independently of the nature of the method used for the determination of the temperature. This trend is confirmed by the comparison with the GEMINI++ statistical model. In contrast, for the QuasiProjectile the observed temperature is lower for the neutron rich system. These results suggest that temperature is sensitive to the N/Z ratio.
