We have performed a kinematically complete experiment on ionization of H2 by 75 keV protonimpact for electrons ejected with a speed close to the projectile speed. The fully differential dataare compared to a three-body distorted wave and a continuum distorted wave?eikonal initialstate calculation. Large discrepancies between experiment and theory, as well as between bothcalculations, are found. These probably arise from a strong coupling between the ionization andcapture channels, which is not accounted for by theory.
