Analysis of the neutron single-particle energies of Zn, Ge, and Se isotopes within a mean field model with dispersive optical potential

The parameters of the neutron dispersive optical potential of even-even Zn, Ge, and Se isotopes (both stable and unstable) are determined from an analysis of experimental and estimated neutron single-particle energies. The imaginary part of the potential depends on the shell structure of the isotopes. The calculated energies are found to be in good agreement with the experimental and estimated energies.
