Abstract：
In this paper the helicity formalism of the angular distributions for processes e⁺e^-→J/ψ→V + X, V→P₁P₂ or V→P₁P₂P₃ and X→PP are given simultaneously. On the basis of the formalism a moment analysis is made and some relations are obtained which can be used for determining the spin J_x of the boson resonance X and the helicity amplitude ratios of the process/ψ→V + X.
