摘要：
The nonperturbative coupled-angular-mode (CAM) method is applied to the treatment of the parallel velocity-assisted charge-transfer process in grazing scattering of alkali-metal ions at Al(111) surface. The neutralization of Na+, K+, and Li+ projectiles is studied. A multistate treatment of the problem including projectile ground and excited states is performed. Calculated neutral fractions in the scattered beam agree on a quantitative level with available experimental results over a wide range of scattering conditions. The role of the population of excited states is discussed.
