Abstract
We give a review of our investigation on the EOS and single-particle properties of asymmetric nuclear matter (ANM) within the framework of the Brueckner-Hartree-Fock (BHF) approach extended by including a microscopic three-body force (TBF). It is shown that inclusion of the TBF improves significantly the predicted saturation property of symmetric nuclear matter within the nonrelativistic BHF framework and leads to a significant stiffening of the density dependence of symmetry energy at high densities well above the saturation density. The TBF may induce a strongly repulsive and momentum-dependent rearrangement contribution to the single-particle (s.p.) potentials in ANM at large densities and high momenta. Both the effect of ground state (g.s.) correlations and the TBF rearrangement contribution are found to be necessary for predicting reliably and realistically the s.p. properties of ANM within the Brueckner approach.
