摘要：
A recently developed single-center model of double photoionization (DPI) of the H-2 molecule [Kheifets, Phys. Rev. A 71, 022704 (2005)] has been extended to represent the DPI process at unequal energy sharing. The model is applied to describe the shape of the fully-differential cross-section (FDCS) of a randomly oriented hydrogen molecule in the isotopic form of D-2 at the kinematics of recent experiments. Comparison with analogous FDCS for the He atom helps to elucidate the molecular effects.
