Elastic and inelastic scattering of Li+ions by He

Abstract

Elastic and inelastic differential measurements of the Li⁺-He system were undertaken with particular attention given to the charge exchange channels. The energy variation of the 'summed' differential cross sections (elastic, inelastic and change exchange) agrees quite well with the published ab initio ground state calculation, showing that most important channels are considered. All the inelastic and charge exchange processes are discussed in the frame of the diabatic correlation diagram.
