Polarization Phenomena in Small-Angle Photoproduction of e+e- Pairs and the GDH Sum Rule

Abstract

We discuss a possibility to measure the spin-dependent part of the forward Compton scattering amplitude through interference effects of the Bethe-Heitler and virtual Compton scattering mechanisms in photoproduction of e+e- pairs at small angles.
