Mar 28, 2011 · The lowest core-excited state was described by the ground state of the N + 1 valence electrons (the additional electron accounts for the promoted core electron) in the field of the core-hole. The high-lying core-excited state manifold is then described by the excitations among the N + 1 electrons within the valence orbital space.
