英文摘要 | Radiative decays of the radially excited charmonium resonance, psi(2S), into pipi, K (K) over bar and etaeta final states have been measured in a sample of 4.02x10(6) psi(2S) events collected by the BES Collaboration. The branching ratios B(psi(2S)-->gammaf(2)(1270))=(2.12+/-0.19+/-0.32)x10(-4) and B(psi(2S)-->gammaf(0)(1710))xB(f(0)(1710)--> K+K-)=(3.02+/-0.45+/-0.66)x10(-5) are obtained. When compared to the corresponding radiative J/psi decays, the observed psi(2S) radiative decay rates into gammaf(2)(1270) and gammaf(0)(1710) are consistent with the prediction of the "12%" rule. |
