“…As seen from the figure, our calculations, based on Eqs. (4)- (6), are in good agreement with the experimental data, except for θ k = 20 • . For this particular angle, the theory of Haug involving Sommerfeld-Maue wave functions gives the best description even though it fails in the range −40 • < θ k < −25 • .…”

“…Most of the studies of atomic bremsstrahlung in the past were dedicated to the properties of the emitted photons, while the scattered electrons remained unobserved. In these works, the angular distribution of the emitted radiation [1][2][3][4][5][6] and its polarization [7][8][9] was investigated. Due to experimental limitations, less attention was paid to setups where the emitted photons and the scattered electrons are observed in coincidence.…”

We present a theoretical study of bremsstrahlung produced by high-energy electrons scattered by heavy atomic targets. Considering coincident observation of the emitted photons and the scattered electrons, we pay special attention to the polarization degree and direction of the outgoing light. To investigate these properties of atomic bremsstrahlung, we apply the density matrix approach and solutions of the Dirac equation. Detailed calculations are performed for initial electron energies ranging from 100 to 500 keV and different fixed electron scattering angles. The results of these calculations are compared with predictions obtained under the assumption that the scattered electrons remain unobserved. This comparison reveals that both the degree and the direction of linear polarization of bremsstrahlung are very sensitive to the direction of the scattered electron.
