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