Abstract
The Born theory for bremsstrahlung from high-energy electrons colliding with extended (finite-mass) nuclei is reexamined. Higher-order effects are included into the Born approximation by making use of the weak-potential Sommerfeld-Maue prescription in an additional contribution to the transition amplitude. Predictions are made for the differential cross section (with respect to the photon degrees of freedom) and for the polarization correlations between the incoming electron and the emitted photon. It is found that at collision energies exceeding 20 MeV the cross section as well as the polarization correlations are strongly influenced by nuclear recoil and nuclear structure effects, particularly at backward photon angles. Numerical results are presented for bremsstrahlung from 10--100 MeV electrons colliding with protons, ${}^{19}$F and ${}^{89}$Y nuclei.
