Abstract

The soft physics approach to Compton scattering at moderately large momentum transfer is reviewed. It will be argued that in that approach the Compton cross section as well as other exclusive observables exhibit approximate scaling in a limited range of momentum transfer. Invited talk held at the workshop on exclusive and semi-exclusive processes at high momentum transfer, Jefferson Lab, May (1999).
