Electron-hydrogen atom collision in the presence of a circularly polarized laser field
Abstract
The basic formalism of Brandi et al. (1978) is used to obtain an expression for the scattering amplitude for elastic and inelastic excitation of hydrogen by electrons in the presence of a circularly polarized laser field. Attention is given to a study of the dependence of the differential and total excitation cross section on the electromagnetic field polarization. It is shown that the electron-impact excitation of the hydrogen ground state to its first excited state, in the presence of an electromagnetic field with absorption (or emission) of specified photons, is enhanced by circularly polarized light.
