Charge transfer in helium in a laser field
Abstract
With use of a diabatic molecular representation in two states, resonant charge transfer in helium in the presence of a laser field has been studied within the semiclassical impact-parameter approximation. The laser-frequency dependence of the charge transfer cross section shows an anomalous-looking feature quite distinct from cases studied earlier involving excitation. An effect of the laser field on the angular distribution of the charge transfer ions is also indicated.
