Photo double ionization of molecular deuterium

A helium-like description of photo double ionization of molecular deuterium is extended to derive a dependence of molecular excitation amplitudes on e lectron energy sharing and dynamical quantum numbers labelling internal mod es of excitation of the escaping electron pair. Both linear and circular po larizations are considered, and predictions regarding circular dichroisms i n the angular distributions of the electron and ion pairs are given. A deta iled comparison of the model with recent (gamma, 2e) measurements is also p resented.
