An Improved Calculation of the Multiphoton Bremsstrahlung Process in the Presence of a Laser Beam

Abstract

It has been noted previously that analyses of free-free transitions in the presence of an ion are appreciably affected by neglecting the Coulomb field of the ion at infinity. We have therefore made here an improved calculation of the cross section for the multiphoton bremsstrahlung process by taking account of the Coulomb field in the initial and final states.
