Configuration Interaction in the Helium Continuum

Abstract

Configuration interaction is applied to the ${}_{}{}^1{}_{}{}^{}P$ helium continuum between the first- and second-quantum thresholds. Discrete configurations are included which give rise to auto-ionization levels (resonances). Differential oscillator strengths are presented for the nonresonant region, while positions, widths, and $q$ values are given for the six lowest-lying resonance levels.
