Results from the Crystal Ball at DORIS II
Description
Results are presented from studies of the inclusive photon spectra in hadronic decays of the UPSILON' and UPSILON and the exclusive channel UPSILON' → γγUPSILON → ααl+l-, by the Crystal Ball detector at DORIS II. We measure two signals in the UPSILON' → γ + anything inclusive channel at E(γ) == 108.3 +- 0.9 +- 3.0 MeV and at E(γ) == 127.5 +- 1.2 +- 4.0 MeV. Branching ratios obtained for these signals are: BR[UPSILON' → γ(108) + anything] == (6.3 +- 1.3 +- 1.4)% BR[UPSILON' → γ(128) + anything] == (6.0 +- 1.3 +- 1.4)%
