The radial dependence of the optical potential for nucleonnucleus scattering is calculated using the empirical nuclear density. The nucleus is locally approximated by the Fermi model. The equation for scattering in the nuclear medium is solved approximately, and the optical potential is expressed using nucleon-nucleon phase shifts. In the numerical computations, the Signell- Marshak phase shifts are used. The effect of the exclusion principle increases the depth of the real part and decreases the depth of the imaginary part of the optical potential in the center of the nucleus. The radius of the real part is practically equal to the radius of the density distribution, whereas the radius of the imaginary part is slightiy larger. Results are compared with experimental estimates of the optical potential. (auth)
