Abstract
The differential cross section for electron-hydrogen atom collisions in the presence of a CO2 laser field is analysed as a function of the incident el ectron energy. We show that the criticism of the second Born treatment of e lastic scattering and excitation by fast electrons is unjustified for vario us geometrical configurations. Detailed calculations of the scattering ampl itudes are performed by using the Sturmian basis expansion.
