Treatment of resonances with the dilated electron propagator: The 2<i>P</i> shape resonance in <i>e</i>-Mg scattering

Abstract

The dilated electron propagator technique based on an underlying bivariational SCF and a second order self-energy is applied to study the 2P shape resonance in e-Mg scattering. Basis set effects are studied and comparisons with the results from an alternative construction of the second order dilated electron propagator are made.
