Sažetak
A new upper limit is presented for the branching ratio (BR) of eta -->3 gamma. This decay is not allowed by charge-conjugation invariance. We have determined that BR(eta -->3gamma)<4x10^-5. We also obtained BR(eta-->Pi^0 gamma-->3gamma)<9x10^-5 ; this decay mode is absolutely forbidden, as it violates conservation of angular momentum. Finally, we have established that BR(eta-->pi^0pi^0 gamma gamma)<1.2x10^-3 in a restricted diphoton-energy region. All three upper limits are at the 90% confidence level. They were obtained by using the Crystal Ball multiphoton spectrometer at the AGS and are based on the analysis of 28 million eta mesons produced in the pi^-p-->eta n reaction close to threshold.
