Abstract：
The doubly radiative decay process J/ψ → γX, X→γV, V→2P (or 3P) is discussed in this paper. For the intermediate state X with various spin-parity J^P, the corresponding helicity formula of angular distribution formulas and the moments developed from the generalized moment analysis are presented. They are useful for determining the spin of the intermediate state.
