摘要：

Total cross sections for single-electron capture from He by keV O+ 2D-degrees and 2P-degrees metastable ions turned out to be much smaller than for O+ 4S-degrees ground-state ions, despite a larger energy defect for the latter reaction. We suggest that this unexpected behavior is caused by efficient suppression of electron capture into either metastable ion due to a competing, collisionally induced inelastic transition into the companion metastable state.
