Temperature dependent relativistic mean field for highly excited hot nuclei - art. no. 054610

The temperature dependent relativistic mean field (RMF-T) results obtained by using nonlinear Lagrangian parameter set NL3 are presented for a few sel ected representative spherical and deformed nuclei. The calculated total bi nding energy (entropy) decrease (increase) as temperature (T) increases. Th e depths of the potentials and the single particle (sp) energies change ver y little with temperature. The density slightly spreads out; as a result th e radius increases as temperature rises. For well deformed nuclei the shell effects disappear at around T similar to 3 MeV. This value of T is relativ ely higher as compared to the corresponding value of T (similar to 1.8 MeV) obtained in the Strutinsky-type calculations. This difference in the value of T is shown to be due to the use of the effective nucleon mass (< the ba re mass) appearing in the Skyrme III interaction or emerging from the RMF L agrangian.
