Optical potentials of nucleons and composite particles with account of Coulomb interaction

The Coulomb interaction effect on the optical potentials of nucleons and compound particles is analyzed in the framework of the Fermi-liquid theory. The long-range character of Coulomb forces leads to a negligible contribution given by the exchange Fock Coulomb terms to the optical potentials of nucleons and compound particles. The direct Hartree Coulomb terms give, besides the standard Coulomb potential, an additional attractive contribution to the nucleon and compound particle optical potentials, because in the nuclear target field the nucleon and the compound particle acquire effective masses which are essentially different from their reduced masses
