Abstract：
Within the isospin dependent Extended Brueckner-Hartree-Fock framework,the three-body force effects on the single particle potentials of a neutron and a proton in isospin asymmetric nuclear matter and their isospin denpendence have been investigated. It is shown that the contribution of the three-body force is repulsive. At low density, i.e., around and below the empirical saturation density, the effect of the three-body force is rather small, while as increasing density, it becomes more and more pronounced. It is also found that at a given density, the three-body effect increases with isospin asymmetry.
