摘　　要：The momentum and isospin dependence of symmetry potential and effective mass in isospin asymmetric nuclear matter is investigated in the framework of the Brueckner-Hartree-Fock approach by adopting the realistic Bonn B two-body interaction in combination with a consistent microscopic three-body force.It is demonstrated that symmetry potentials at the normal density for different asymmetry parameters are in good agreement with the empirical value constrained by the experimental data,and the neutron and proton effective masses show strong isospin splitting with m*n > m*p on the whole range of asymmetry parameters.In the end,the density dependence of the Landau mass is displayed.
