The nucleon differential elastic scattering cross sections, the total proton reaction cross sections, and the
single-particle energies of nucleon bound states for 40Ca, 90Zr, and 208Pb nuclei are reanalyzed in terms of the
dispersive optical model at energies ranging from -75 MeV to 60 MeV. The resultant real effective Woods-Saxon
potential, which corresponds to the dispersive potential, is studied as dependent on A, Z, and E and on projectile
specie (proton or neutron). For the first time, a parameterization of the Woods-Saxon real part of the nucleon-
nucleus optical potential is proposed for the 40
