Photo double ionization of molecular deuterium

Abstract

A helium-like description of photo double ionization of molecular deuterium is extended to derive a dependence of molecular excitation amplitudes on electron energy sharing and dynamical quantum numbers labelling internal modes of excitation of the escaping electron pair. Both linear and circular polarizations are considered, and predictions regarding circular dichroisms in the angular distributions of the electron and ion pairs are given. A detailed comparison of the model with recent (,2e) measurements is also presented.
