Single-photon double ionization of H2 molecule away from equilibrium: A showcase of two-centre electron interference

Serov, V V; Ivanov, Igor; Kheifets, Anatoli


We demonstrate the effect of two-center interference on single-photon double ionization [double photoionization (DPI)] of the aligned H2 molecule when it shrinks or expands from the equilibrium internuclear distance. This interference affects the first stage of the DPI process in which the primary photoelectron is ejected predominantly along the polarization axis of light and its geometrical interference factor is most sensitive to the internuclear distance in the parallel (Σ) orientation of...[Show more]
