AbstractAbstract
[en] We extend our previous study of electron Coulomb Bremsstrahlung in the presence of a laser field from the case of the spectrum ds/dωx to the case of the photon angular distribution d2σ/dωxdΩx. Going to electron energies up to 50 keV, much higher than in the previous calculation, we include retardation in the description of the spontaneously emitted photon. In our semiperturbative approach, the presence of the laser field modifies the shape function of the spontaneous emission of a single photon of frequency ωx, defined as the ratio S (d2σ/dωxdΩx)/(dσ/dωx), and leads to processes in which laser photons are emitted and absorbed simultaneously with the X photon emission. Numerical results will be presented for the frequency of the CO2 laser field (ωL = 0.117 eV) and intensities up to 10-6 a.u. (authors)
