Satellite structure in laser-assisted charge-transfer cross sections

Abstract

A six-state coupled-channel calculation has been performed on the laser-assisted charge-transfer collision ${\mathrm{H}}^{+}$+Na+ħω. A greatly enhanced charge-transfer cross section is observed for low-energy collisions if the photon energy is matched to the classical satellite frequency. This frequency is determined by the location of an extremum in the difference of potential energies between the laser-pumped initial and final molecular states. The stationary-phase method has been used to reproduce the general features and the magnitude of the cross-section structure.
