摘　　要：Based on the finite temperature Brueckner-Hartrec-Fock approach including a microscopic three-body force, the rearrangement correction V2(k) to the single nucleon potential in hot nuclear matter, and its density and temperature dependence have been investigated by using the hole-line expansion for the mass operator.Based on the finite temperature Brueckner-Hartree-Fock approach including a microscopic three-body force, the rearrangement correction V2（κ） to the single nucleon potential in hot nuclear matter, and its density and temperature dependence have been investigated by using the hole-line expansion for the mass operator. The calculated result is given in Fig.1. It is seen from Fig.1 that the rearrangement contribution due to the ground state correlations is repulsive and it depends sensitively on both density and temperature.
