Abstract
A recently derived dispersive optical model potential (DOMP) for $^{208}\mathrm{Pb}$ is extended to consider the nonlocality in the real potential and the shell gap in the definition of the nuclear imaginary potentials near the Fermi energy. The modified DOMP improves the simultaneous description of nucleon scattering on $^{208}\mathrm{Pb}$ and of the $^{208}\mathrm{Pb}$ particle-hole bound states. This potential is shown to give a very good description of nucleon scattering data on near-magic targets $^{206,207}\mathrm{Pb}$ and $^{209}\mathrm{Bi}$.
