The Auger electron emission from C/sup 3+/ and C/sup 2+/ ions after double-electron capture from He, H/sub 2/, and Xe atoms in a single collision with C/sup 5+/ and C/sup 4+/ ions and after one-electron capture into K-shell excited C/sup 4+/ ions was measured under zero degrees with high resolution. The nl, n'l' distribution of doubly excited states induced by capture are discussed in the framework of previously established classical over-barrier and Landau-Zener models. Evidence for two-electron transfers in a one-step process is outlined. The spectral features indicate spin conservation during capture, electron transfers with core excitation, contributions from endoergic capture, post-collision line broadenings, and cascade channels.
