The radial dependence of the optical potential for nucleon-nucleus scattering is calculated using the empirical nuclear density. The nucleus is approximated locally by the Fermi model. The equation for the scattering in the nuclear medium is solved approximately, and the optical potential is expressed using nucleon -nucleon phase shifts. In the numerical computations, the latest Yale phase shifts are used. In comparison with the analogical calculation based on the Signell-Marshak phase shifts, the radius and the surface thickness of the real and the imaginary part of the optical potential practically do not change; depths of the optical potential increase a little (less than 8%, i.e., less than 2 Mev) for the imaginary part and up to 35%, i.e., up to 15 Mev, for the real part, in the center of the nucleus.
