Abstract
Absolute cross sections, differential in angle and energy of the scattered particles, are obtained for single charge transfer and elastic scattering of He2+ from He for incident ion energies 200 eV to 600 eV and lab angles 2.5 degrees to 20 degrees . No ground state He+ are found and oscillations due to double charge transfer are observed in the elastic channel. These data are interpreted in terms of 1 Sigma g+ and 1 Sigma u+ potentials in the incident channel and curve crossings of this 1 Sigma g+ potential with higher states.Keywords
