Abstract：
The perturbative QCD prediction of “15% rule” for the ratio of ψ(2S) to J/ψ hadronic decay rates suffers seveal apparent approximations. Calculations using existing experimental data are made in this paper; further corrections to this radio for a number of exclusive decay channels are also discussed.
