State-selective differential single-electron-capture cross sections for O2+-He collisions
Abstract
Energy-gain spectra for single-electron capture by O2+ ions colliding with He have been measured at laboratory energies between 60 and 200 eV, and scattering angles between 0° and 4°. The spectra indicate that the predominant exit channel is the (2p3 2P) excited state of O+. Differential cross sections for capture into the (2P) state were also measured. The data show an oscillatory structure. The measurements are in qualitative agreement with recent theoretical calculations based on a full quantum-mechanical description.
