Non-variational, spline-Galerkin calculations of resonance positions and widths, and photodetachment and photo-ionization cross sections for H^-and He

Abstract

A non-variational Galerkin method, completely based on B-spline methods is introduced and applied to calculations of resonance positions and widths in H- and He. The results agree very well with other theories and experiments. Photodetachment in H- and photoionization of He are also considered.
