Postcollisional effects in multiple ionization of diatomic molecules by ion impact

Multiple electron ionization of diatomic molecular targets is studied for impact of proton beams. It is shown that for these molecular targets, as it was previously predicted for atomic ones, postcollision Auger type emission following inner-shell vacancy production dominates the reaction at high enough impact energies. Moreover, it is proven that this dominance increases as the ionization degree increases.
