Abstract
The dependence of the nuclear temperature on the source neutron-proton () asymmetry is experimentally investigated with the intermediate mass fragments (IMFs) generated from thirteen reaction systems with different asymmetries, on and on at 40 MeV/nucleon. The apparent source temperatures for these systems are determined from the measured IMF yields from the intermediate velocity sources using eight carbon-related double isotope ratio thermometers. A rather weak asymmetry dependence of the source temperature is qualitatively inferred from the extracted asymmetry dependence of the apparent temperature and that of the relative temperature change by the sequential decay effects with the help of the theoretical simulations. The present result is compared with those from other available experiments.
