Abstract
Absolute total cross section measurements and state-selective translational energy spectroscopy have been performed for single electron capture by 0.5-9 keV C2+ from H2, He and Ar, for the C2+ ground state as well as the C2+ metastable state. The experimental results are compared with available data obtained with undefined metastable primary ion beam fractions. For the particular case of C2+-H2 collisions, experimental results could be explained by close-coupling calculations involving empirically derived coupling matrix elements and Franck-Condon factors for H2 ionization via electron capture.Keywords
