Abstract：
This paper gives the relation between the helicity formalism(HF) and the effective interaction formalism (EIF) for the process e ⁺e ^－→J/ψ→γB,B→P ₁P ₂.The angular distributions of the pseudoscalar meson for different spin (J=2,4) of B indicate that there exist sensitive and insensitive regions to determine the spin of B.Unfortunately the data of θ/f ₂(1720) and ξ(2230) just fall into the insensitive region.
