Large-angle inelastic electron-hydrogen scattering in the Glauber approximation

Large-angle inelastic scattering is considered using the Glauber approximation for the scattered wave function, but without the additional approximation of purely transverse linear momentum transfer. At large angles, the electron-proton interaction dominates and has Rutherford $q^{-4\mathrm{}}$ behavior. Furthermore, with the direction of $\overrightarrow{\mathrm{q}}$ unrestricted the $\mathrm{L}\mathrm{y}-\alpha$ radiation is found to be, in general, elliptically polarized.
