Inverse bremsstrahlung absorption in large radiation fields during binary collisions-born approximation. I. Elastic collisions

The absorption of radiation by inverse bremsstrahlung absorption from a planar single mode monochromatic light beam is considered by nonrelativistic time-dependent perturbation theory, which is equivalent to the Born approximation. The results are of general validity and may be applied to any scattering system which is left unchanged by the collision. Comparison between the results obtained previously by different workers shown the relationship between the different models used to investigate this effect.
