Abstract：
The formalism and technique of the moment method for spin analysis of the boson X in J/ψ→γX,X→P₁P₂ are presented.The analysis technique is cited to study the spin of θ(1720) with Monte Carlo data samples.One finds that the spin of the boson X can be effectively determined by the moment method.As an example,the technique is used to measure the spin of the resonances in the low mass region of J/ψ→γK⁺K^－ channel at BES.It is found that the spin analysis strategy of the moment method is successful.
