g-Hartree mean-field analysis of inner-shell many-body effects for small- and large-Z atoms

The authors analyse the atomic many-body effects associated with single-electron excitations within the g-Hartree framework: g values are determined which exactly reproduce inner- and outer-shell ionisation energies for the whole periodic table. Average g values are then used to compute physical observables for several channels within a mean-field analysis. The results obtained, particularly for large-Z atoms, give excellent agreement with experiment.
