Relationship Between Measurement Of Nuclear Temperature And Energy Of Particles

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 from 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 with increasing energies of emitted particles. It is demonstrated that hot nuclei with higher temperature are more probable to emit higher energy particles.
