The direct hadronic decay amplitude J hadrons can interfere with the decay amplitude via one photon, J1 hadrons. We show how this might be useful. A definite pattern of coherence or incoherence of direct and 1 decay amplitudes could test theoretical explanations for the small J width. It should also prove possible to extract meson and baryon electromagnetic form factors at Q2=mJ2.
