摘要：

We studied the single-electron capture as well as the direct processes occurring when a He2+ ion is scattered by a He target. Doubly differential cross sections were measured for single-electron capture with a collision energy ranging from 2 to 8 keV and a scattering angle varying from 10' to 3-degrees-30' (laboratory frame). Single-electron capture into excited states of He+ was found to be the dominant process, confirming the experimental study of Afrosimov et al. Elastic scattering and ionization differential cross sections were measured for E = 6 keV.
