Abstract：
The processes e⁺e^－→J/ψ→γ+X, X→pp are discussed usiag the generalized moment analysis method. The moment expressions of the above processes are given, And they are used to detennine the spin of the resonance X decaying to pp. The helicity arnplitude ratios of the ahove processes in terms of moment expressions are also given.
