Electron propagator theory (EPT) is applied to calculating vertical ionization energies of the anions F-, Cl-, OH-, SH-, NH,, PH,-and CN-. Third-order and outer valence approximation (OVA) quasiparticle calculations are compared with AMBPT( 4) (MBPT, many-body perturbation theory) results using the
