Effect of the Imperfectly Closed Proton Shell inZr90on Elastic Electron Scattering

Abstract

Although density-dependent Hartree-Fock theory based on a realistic interaction with essentially no free parameters yields satisfactory agreement with elastic electron scattering for reasonably well-closed shell nuclei like ${}_{}{}^{40}{}_{}{}^{}\mathrm{Ca}$ and ${}_{}{}^{208}{}_{}{}^{}\mathrm{Pb}$, an additional correction arises in the case of an imperfectly closed shell. Inclusion of this correction term in ${}_{}{}^{90}{}_{}{}^{}\mathrm{Zr}$ significantly improves agreement with experimental data.
