Abstract
Evidence is presented for the production of states () in the reaction with subsequent decay of the into or . The data were obtained with the nonmagnetic CUSB detector at the Cornell storage ring. Observed were 14 (15) events consistent with the transition to the with an estimated background of 1.7 (1.3) events. The lower-energy photons cluster around 100 MeV, implying MeV. A single-line interpretation of the lower-energy photon spectrum is disfavored.
