Abstract

The Dirac-Sommerfeld-Maue (DSM) theory for electron bremsstrahlung at the short-wavelength limit, based on a point-Coulomb description of the target nucleus, is tested against the Dirac partial-wave (DW) theory at collision energies up to 35 MeV. It is found that for the small photon angles, which contribute to the angle integrated bremsstrahlung yield, the screening effects are at most in the percent region. Predictions are made for the nuclear charge dependence of the singly differential bremsstrahlung cross section at 500 MeV, where experiments are planned in the near future.
