Theoretical studies on slow collisions between medium-z metallic ions and neutral H, H2, or He

The database on electronic transitions in slow collisions between medium-Z metallic ions and H, H2, and He targets is examined. Semiclassical close-coupling calculations are presented for electron transfer in Si4+ -H, Ni10+ -H, Si4+ -H, Ti4+ -He, Ti4+ -H2, and Fe8+ -H2 collisions in an energy range of about 1-100 keV/u. The calculated distributions of electron transfer over the final states of the projectiles are discussed. For the case of Si4+ -He collisions, we also assess the process of target excitation.
