We investigate the relativistic Hartree-Fock single-particle potential in the framework of a local density approximation and of an improved local density approximation. In most cases the latter yields a better agreement between theoretical and experimental results for quantities which are characteristic of the nuclear surface. In the case of /sup 40/Ca, the energy dependence of the ratio of the strengths of the scalar and vector components of the relativistic potential in the center-of-mass system is in good agreement with that determined by the elastic scattering data analyses. In keeping with recent experimental evidence, the calculated central part of the optical-model potential has a wine-bottle bottom shape at intermediate energy. Both approximations provide a strong spin-orbit component.
