The radial dependence of the optical potential for nucleonnucleus scattering is calculated with the help of the empiri-cal nuclear density. The nucleus is approximated locally by the Ferml model. The equation for the scattering in the nuclear medium is solved approximately, and the optical potential is expressed with the help of 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 slightly bigger. The results are compared with the experimental estimates of the optical potential. (auth)
