Dispersive optical model description of nucleon scattering on Pb-Bi isotopes

Abstract

A recently derived dispersive optical model potential (DOMP) for ${}^{208}$Pb is extended to consider the non-locality 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 ${}^{208}$Pb and of the ${}^{208}$Pb particle-hole bound states. The new potential is shown to give a very good description of nucleon scattering data on near-magic targets ${}^{206,207}$Pb and ${}^{209}$Bi.
