Nonresonance spontaneous bremsstrahlung of an electron scattered by a nucleus in a pulsed light field

The paper presents a theoretical study of nonresonance spontaneous bremsstrahlung of an electron scattered by a nucleus in the field of a pulsed light wave. The approximation is considered when a pulsewidth is considerably large than the characteristic time of the wave oscillation. The analytical expressions for the amplitude and cross-section of nonresonance spontaneous bremsstrahlung of an electron scattered by a nucleus in the moderate pulsed light field are derived. It is concluded, that for process spontaneous bremsstrahlung of an electron scattered by a nucleus in the field of pulsed light wave the distribution of stimulated emission (absorption) probability over the number of wave photons has the significant shift to small values relatively corresponding distribution in the case monochromatic wave.
