Remark on the kinematics of the one-photon production in electron-proton scattering

Abstract

I clarify the mistakes in the original version hep-ph/9705427 about the phase space factor for the one-photon production in electron-proton scattering and confirm that the earlier result given by Kroll, Schürmann and Guichon is right.
