A Young double-slit experiment using a single electron source: Oscillations in the angular distribution of Auger-line width

We present evidence for two-center interference effects in the autoionization of a Helium atom following a double capture process in a He2+ + H2 collision, by looking, not at the total intensity as in a previous article [1], but at the full width at half maximum of the energy distribution at a function of the observation angle.
