Abstract
The authors develop a theoretical framework for investigating charge-transfer processes occurring during the scattering of an ion from a solid surface, in the presence of a pulsed laser field. The theory is based upon the many-electron formalism, previously used by their group, to investigate charge transfer based upon purely electronic mechanisms, but it is here extended to include the additional matrix elements needed to describe laser-assisted transitions. The model is applied to several systems with different scattering behaviours, with the conclusion that the effect of the laser field can be expected to be greatest when the target substrate is one with a relatively narrow valence band.
