Phys. Rev. A 71, 022713 (2005) [5 pages]Collision mechanisms in one-electron capture by He2+ ions in collisions with hydrocarbonsReceived 1 November 2004; published 18 February 2005 Translational energy spectroscopy has been used to study one-electron capture by 200–2000 eV amu−1 He2+ ions in CH4, C2H4, and C2H6. The main He+(n,l) excited product channels have been identified and their relative importance assessed. Although significantly different patterns of behavior are observed, all three cases exhibit the highly selective nature of the electron capture process in spite of the large number of possible nondissociative and dissociative product channels associated with a wide spread in energy defects ΔE. © 2005 The American Physical Society URL:
