Av. Korol et al., THEORETICAL TREATMENT OF THE BREMSSTRAHLUNG PROCESS IN THE VICINITY OF GIANT ATOMIC RESONANCES, Physical review. A, 53(4), 1996, pp. 2230-2238
The frequency and the angular distributions of photons emitted in the
bremsstrahlung process of a 0.2-10 keV electron in collision with Ba a
re calculated for the photon frequencies above the 4d threshold: omega
w=100-200 eV. The polarizational bremsstrahlung is taken into account
. A simple method is described for the approximate calculation of the
polarizational bremsstrahlung cross section. This method is particular
ly efficient in the case, when the many-electron correlations are impo
rtant.
