摘要	We have performed kinematically complete experiments on single-electron capture in slow He2+-Ar collisions. Besides the pure capture to the He+(n = 2) level, capture into the deep He+( n = 1) state with simultaneous excitation of another target electron is also observed. In contrast to the pure capture, the total cross section for this two-electron transition decreases with increasing collision energy, and its angular-differential cross section exhibits a much slighter slope. We take these observations as evidence for electron capture mediated by electron-electron interactions.
