Title: Laser-field enhanced electron transfer in p-Ne and p-Ar collisions

Abstract

Electron transfer in the presence of a laser field is considered for the p-Ne and p-Ar collision systems. The calculations are based on a time-dependent density functional theory framework and the basis generator method for orbital propagation. Significant enhancements of electron transfer at low collision energy are found and interpreted with the help of molecular potential curves. For the p-Ar system a moderately intense field at 800 or 1064 nm wavelength is sufficient to increase the total cross section by more than a factor of 2. Contrary to previously studied cases this scenario can be realized and tested in the laboratory.
