Abstract
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.
