Abstract
Reports on q quasi-molecular study of collisionsl processes in the Li+-He system in the laboratory energy range 0.3 keVlab0), diabatic states displaying quasi-symmetric properties (u, g) are introduced. The study of the excitation sharing between the 2p levels of He and Li is carried out within the Demkov-Meyerhof model, and excitation of He(1s2s) is explained in analogy with a similar process in the He-He collision. Analysis of the K-vacancy-sharing process leading to Li(1s2/2l') is undertaken within a many-electron framework. The necessity of creating a double 2p sigma vacancy prior to the Demkov-Meyerhof K-vacancy sharing is confirmed. The calculations are compared with available experimental data and previous theoretical results.Keywords
