Abstract
Estimates for the quantum electrodynamical (QED) and dispersion effects on the spin asymmetry of perpendicularly polarized electrons scattered from a nucleus are given. The QED effects are calculated nonperturbatively in terms of their respective potentials. For dispersion, the transient nuclear excitations of with low multipolarity and energy below 30 MeV are accounted for. Collision energies up to 1 GeV are considered. The results can help to explain the measured spin asymmetry near 1 GeV at forward angles.
