文摘

The spin asymmetry in the scattering of highly relativistic spin-polarized electrons from inert nuclei is calculated by means of a coherent superposition of the electric and magnetic transition amplitudes. The potential scattering is treated with the help of a phase shift analysis while the elastic magnetic scattering is described within the Born approximation. With the exception of longitudinally spin-polarized electrons, the spin asymmetry is generally found to be reduced when magnetic scattering is taken into account. Predictions are made for 20-100 MeV electrons scattering from the spin nuclei ¹H, ¹⁹F, ³¹P and ²⁰⁷Pb.
