Thaler, Jonathan J. Garren, Lynn Adele 2011-07-06T19:41:25Z 2011-07-06T19:41:25Z 10000-01-01 1982 In an experiment performed at the Alternating Gradient Synchroton at Brookhaven National Laboratory, we searched for narrow resonances in the reaction pi minus p -> X n, X -> gamma gamma at 13 Gev. We used a double arm spectrometer with lead glass and scintillation elements. No resonances were observed above mass 2.8 in the gamma gamma spectrum. The upper limit for the eta c cross section tines branching ratio is 23 pb.
