Type: article

Abstract: The isospin dependence of temperatures is investigated in the reactions 78 Kr+ 40 Ca and 86 Kr+ 48 Ca at 10 AMeV. These reactions were studied in the context of the ISODEC experiment, performed at INFN-Laboratori Nazionali del Sud in Catania, by using the 4 π multidetector CHIMERA. The results of the data analysis suggest that the temperature depends on the N/Z ratio. Different thermometric methods,as well as the slope and fluctuations thermometer with the alpha particles as probe and the double isotope yields ratio thermometer are used to extract the temperature of compound nucleus. Higher values of the temperature were observed for the neutron rich system compared to neutron poor one. This trend is confirmed by the comparison with the GEMINI++ statistical model.
