| 英文摘要 | The single-nucleon potential in hot nuclear matter is investigated in the framework of the brueckner theory by adopting the realistic argonne v-18 or nijmegen 93 two-body nucleon-nucleon interaction supplemented by a microscopic three-body force. the rearrangement contribution to the single-particle potential induced by the ground state correlations is calculated in terms of the hole-line expansion of the mass operator and provides a significant repulsive contribution in the low-momentum region around and below the fermi surface. increasing temperature leads to a reduction of the effect, while increasing density makes it become stronger. the three-body force suppresses somewhat the ground state correlations due to its strong short-range repulsion, increasing with density. inclusion of the three-body force contribution results in a quite different temperature dependence of the single-particle potential at high enough densities as compared to that adopting the pure two-body force. the effects of three-body force and ground state correlations on the nucleon effective mass are also discussed. |
