Abstract
We have examined all two-body, elastic-scattering amplitudes in quantum electrodynamics. Aside from the photon-pole contribution, the amplitude for any elastic process is imaginary and proportional to in the limit with held finite. The coefficients of , to the lowest nonvanishing orders of , can be expressed simply in terms of "impact factors." The results contradict both the Regge-pole model and the droplet model in their most straightforward interpretations.
