Abstract：
A convenient generator, based on the existing framework of BES simulation, applicable generally to both ψ′ and J/ψ decays of VP and PP modes, is established. The corresponding angular distribution is taken into account. A similar generator is also established for the successive J/ψ decay in the process of ψ′→X+ J/ψ. In the measurement of branching ratios for ψ'→γη, γη′, ωπ ^o, π ⁺π ^－, K ⁺K ^－, this generator is used to determine the selection efficiency and estimate the background.
