A priori calculation of the 1s and 2s hole states in neon

Abstract

The 1s and 2s electron binding energies in Ne are calculated from the Hartree-Fock and Fock-Dirac energies of Ne( 1S 0), Ne +( 2S, 1s-hole) and Ne + ( 2S, 2s-hole). Correlation energies are estimated from the work of Nesbet and of Oksüz and Sinanoǧlu. Close agreement with recent experimental data is found for both binding energies.
