Abstract：
A possibility to search for the isoscalar 1^－+ exotic state through the J/ψ decay process J/ψ→V+X,X→a₂+π at BEPC/BES is discussed in two cases of single state and two-state coupling.The results show that this possibility is existent both in J/ψ radiative decay and hadronic decay processes.
