Abstract
We define the new description of the electromagnetic current to hold the current conservation in the momentum-dependent Dirac fields from the Ward Takahashi identity. To describe the momentum-dependence we solve the relativistic Hartree-Fock approximation by using the one-pion exchange. In addition we discuss on contribution from the one-pion exchange current and the core polarization. It is shown that this current can reduce the convection current in the isovector case, whose value has been too big due to the small effective mass in the usual relativistic Hartree approximation.
