Abstract

Equation of state of hot nuclear and neutron matter are calculated in the frame of the Thomas-Fermi approximation using of the effective nucleon - nucleon interaction of Myers and Swiatecki in the new approach. The effect of temperature on effective mass, pressure, entropy and binding energy is discussed. A critical temperature of 17.4 MeV for symmetric nuclear matter is found and there is no phase transition in the neutron matter systems. The results of calculations are in good agreement with experimental prediction and other theoretical results.

 

Key words: Nuclear matter, nuclear structure models and methods, nuclear matter aspects of neutron stars, nucleon–nucleon interactions.
