Description

The semi-realistic nucleonic interaction, particularly M3Y-P6 [1], has been shown to describe single-particle potentials from negative energy [2] to relatively high energy (+80MeV) [3] well, within the self-consistent mean-field (or Kohn-Sham) framework. Based on this success, the nuclear equation of state at finite temperature with M3Y-P6 is provided, which is compatible with the low-energy experiments and may be useful, e.g., for studying the supernovae. Its advantage for the spin properties [4,5] will also be mentioned.
