Abstract

Doubly differential cross sections, in energy and angle, for state-selective single-electron capture by Ne3+, Ne4+ ions from Ne, and Ne6+ ions from He have been measured at laboratory impact energies between 60 and 600 eV and scattering angles between 0 degrees and 5 degrees. The measurements show that the angular distributions of the reaction channels with large energy-gain values are shifted towards larger scattering angles as would be expected. The energy-gain spectra are interpreted qualitatively in terms of the reaction window, which are calculated using the single-crossing Landau-Zener model.
