Book Description
A sample of 1.8 x 106 produced psi's collected by the Crystal Ball detector at SPEAR is used to measure branching ratios of selected radiative psi' decays to non-charmonium states which decay into photons. A sample of 2.2 x 106 produced J/psi's is used to measure the same radiative decays from the J/psi. The ratios BR(psi' .-->. .gamma.f)/BR(J/psi .-->. .gamma.f) = 9 +- 3%, BR(psi' .-->. .gamma.theta)/BR(J/psi .-->. .gamma.theta) 10% - 15%, BR(psi' .--. .gamma.eta)/BR(J/psi .-->. .gamma.eta) 1.8%, and BR(psi' .--. .gamma.eta')/BR(J/psi .-->. .gamma.eta')

Book Description
Radiative decays of the radically excited charmonium resonance, [psi](2S), into [pi][pi], K{bar K} and [eta][eta] final states have been measured in a sample of 3.96 x 106 [psi](2S) events collected by the BES collaboration. The branching ratios B([psi](2S) 2![gamma]f2(1270)) = (2.27 ± 0.26 ± 0.39) x 10−4 and B([psi](2S) 2![gamma]f0(1710)) x B(f0(1710) 2!KK−) = (5.59 ± 1.12 ± 0.93) x 10−5 are obtained. When compared to the corresponding radiative J/[psi] decays, the observed [psi](2S) radiative decay rates into [gamma]f2(1270) and [gamma]f0(1710) are consistent with the ''15%'' rule.
