Abstract The single-particle potentials in isospin asymmetric nuclear matter is investigated in the framework of the Brueckner theory by adopting the realistic Bonn B two-body interaction in combination with a consistent microscopic three-body force. The rearrangement contribution induced by the ground state correlations to single-nucleon potentials is calculated in terms of the hole-line expansion of the mass operator. With the modification of this rearrangement term the symmetry potential is discussed as a function of momentum for several isospin asymmetries.
