The influence of isospin on thermometric properties is examined in the reactions 78Kr + 40Ca and 86Kr + 48Ca at 10 AMeV. These reactions were realized as part of the ISODEC experiment at INFN-LNS (Laboratori Nazionali del Sud) in Catania, utilizing the 4π CHIMERA multidetector. The analysis of the collected data indicates a correlation between temperature and the N/Z ratio. Two thermometric approaches were employed to determine the temperature of different sources: the slope thermometer using alpha particles as a probe and the double isotope yield ratio method. The findings reveal that depending on the source, isospin affects the temperature differently. For example, for the compound nucleus source, the neutron-rich system exhibits higher temperatures compared to the neutron-poor one and this trend is further validated through comparisons with the GEMINI++ statistical model.
