Double photoionization of neon

Abstract
A calculation of the double photoionization of neon using many-body perturbation theory has permitted a quantitative study of the relative importance of various contributing effects, i.e., ground-state correlations, inelastic internal collisions, core rearrangement, and a virtual Auger transition. The results are in good agreement with experimental data. The energy distribution between two outgoing electrons and the ratio of double to single photoionization are calculated and discussed.
