Polarization correlations between the incident electron, the emitted photon and the recoiled electron of bremsstrahlung from atoms are discussed for incident electrons of kinetic energy T1 = 50 keV. It is an exact numerical nonrelativistic calculation in a partial-wave formulation. In the nonrelativistic theory, all the polarization correlations vanish except those related to photon polarizations. Our results show that the atomic-electron screening effect is small on the polarization correlations except for hard photons and for heavy atoms. When the Coulomb parameter is large, the nonrelativistic Born approximation is not good, as expected.
