Abstract
We compute the branching ratio for and in chiral perturbation theory and find that both decays should be observable at CEBAF. With sufficiently low thresholds on the invariant mass a branching ratio of may be observed for . For the decay mode we predict a branching ratio of . The dependence of the M1 and E2 amplitudes on the momentum transfer will provide a useful test of chiral perturbation theory which predicts variation over the allowed kinematic range.
