Abstract
We suggest here the presence of a J=0 fixed pole in the virtual Compton amplitude A2 with a residue linear in the photon mass q2 for all q2. The resultant sum rule is found to be consistent with the on-mass-shell (q2=0) data, the scale-invariance requirement at q2→∞, and the electron scattering data for intermediate q2.
