Numerical Hartree–Fock energies of singly charged cations and anions with N≤54

Abstract
Numerical Hartree–Fock (NHF) calculations have been performed for the singly charged cations Li+–Cs+ and anions H–I in their ground states. For the cations, the NHF values in the literature are found to be insufficiently accurate, while for the anions our NHF study covers the whole series H–I (except Sc and Pd) for the first time. Atomic ionization potentials and electron affinities are computed and compared with experiment.
