Abstract: (APS)
The pion-exchange contributions to the two-photon amplitude are derived and gauge invariance of the complete amplitude is shown. A low-energy theorem for a general two-photon process is derived and the pionic contribution to the magnetic susceptibility is calculated. The contribution of this quantity to n−p two-photon radiative capture is shown to be small.
