Abstract

Radiative decays of the radially excited charmonium resonance, Ψ(2S), into ππ, KK̄ and ηη final states have been measured in a sample of 4.02×10⁶ Ψ(2S) events collected by the BES Collaboration. The branching ratios B(Ψ(2S)→γf ₂(1270))=(2.12±0.19±0.32) × 10^-4 and B(Ψ(2S)→γf₀(1710))×B(f₀(1710) →K⁺K^-=(3.02±0.45±0.66)×10 ^-5 are obtained. When compared to the corresponding radiative J/Ψ decays, the observed Ψ(2S) radiative decay rates into γf ₂(1270) and γf₀0(1710) are consistent with the prediction of the "12%" rule.
