Two-source double-slit interference in angle-resolved high-energy above-threshold ionization spectra of diatoms
When an electron from a diatomic molecule undergoes rescattering-tunneling ionization, a novel form of destructive interference can take place that involves all four geometric orbits that are available to the electron when it is freed, because both ionization and rescattering may take place at the same or at different centers. We find experimentally and confirm theoretically that in orientation-averaged angle-resolved high-order above-threshold ionization spectra the corresponding destructive interference is visible for O2, but not for N2.
