Potential scattering of slow electrons in a laser radiation field

Potential scattering of slow electrons in a weak external electromagnetic field is considered. An expression connecting the amplitude of n-photon forced bremstrahlung (FB) and elastic scattering for electrons beyond the frames of Born approximation is obtained. Numeric calculations of cross section of multiphoton FB during electron scattering on model potentials are carried out. The results of calculations of cross sections of one-photon FB with calculations according to known formulae are compared
