摘　　要：The possibility to search for the isoscalar 1-+exotic state through the J/ψdecay process J/ψ→ω+X,X→V+V at upgraded BEPC(Beijing Electron-Positron Collider)/BES(Beijing Spectrameter)is discussed for two cases:single state and multi-state coupling in terms of the generalized moment analysis method.The results show that this possibility exists only for the case of single state case.

关 键 词：method. SCALAR state
