Abstract
The triply differential cross section of unpolarized bremsstrahlung produced by polarized electrons in the Coulomb field of a nucleus is calculated with the aid of SommerfeldMaue wave functions The photon asymmetry originating from transversely polarized electrons is calculated for various values of energies and angles in particular for the parameters of recent experiments As a function of the atomic number Z of the target nucleus the asymmetry shows a distinct deviation from a linear dependence in contrast to a previous calculation exact to lowest order in the Coulomb parameter Z/137 The crosssection formula is integrated numerically over the angles of the outgoing electrons to obtain the photon asymmetry observed in noncoincidence experiments
