Abstract：
The process e⁺e^－→J/ψ→V+X(J^PC), X(J^PC)→3P is studied using the generalized moment analysis method. The complicated structure of the resonance peak is discussed by use of multi-states coupling modes and some relations of moments are obtained. The coupling mode of the wide resonance peak can be determined by analysing the experimental data. The masses, widths and spins and so on of these states can also be determined.
