Abstract
Temperature of 5MeV was extracted from double isotope ratios [GRAPHICS] measured at backward angle in laboratory system in the reaction 30MeV/u Ar- 40 + Ag-nat. It is observed that this temperature increases continuously fr om 5MeV to 6MeV with the increase of the energy threshold E-cut/A. A Monte Carlo simulation on particle emission process of hot nuclei shows that the average temperature of hot nuclei as emission sources goes up gradually wit h increasing energies of emitted particles. It is demonstrated that hot nuc lei with higher temperature are more probable to emit higher energy particl es.
