Abstract：
The experimental method for spin-parity analysis of x in the radiative decay of J/ψ→γ+x has been studied with data generated by the Monte-Carlo method where x is a system of two pseudoscalars.As an example the results of J/ψ→γθ(1720),then θ(1720)→K^－+K⁺ are presented.The uniqueness of valid theoretical hypothesis for various fitting results and the sensitive region of this method are discussed.
