State-selective single-electron capture by 80 keV C4+ions from He, H2and Li

Abstract
Absolute excitation cross sections for single-electron capture into selected n, l states have been determined by VUV spectroscopy for impact of 80 keV C4+ on He, H2 and Li. For all three collision systems the predominant final ion states belong to one or two electronic shells only. Within such shells a preferential population of higher l sublevels is found.
