Abstract

Total electron-capture cross sections have been measured for collisions of Alq+ (q=210) with H and H2 in the 20120-eV/amu energy range. The general trend of the cross sections for both H and H2 is an approximately linear increase with ionic charge state. The Al²⁺+H and Al³⁺+H systems were investigated theoretically using the molecular-orbital method with a pseudopotential to represent the Al³⁺ ion core. Coupled-channel calculations realize good agreement with experiment. An anomalously small cross section for Al²⁺+H is attributed to the fact that of the 1 and 3 entrance channels, only the 1 molecular state contributes to the cross section. © 1985 The American Physical Society.
