Abstract：
In this paper the structure of the wide resonance θ(1720) produced in J/ψ radiative decay is studied by using moment analysis.Since the f' ₂(1525) and θ(1720) resonances overlap in this mass region,two three-states coupling structure modes 2 ⁺⁺(f' ₂(1525))+0 ⁺⁺+0 ⁺⁺and 2 ⁺⁺(f' ₂(1525))+0 ⁺⁺+2 ⁺⁺are discussed.It is helpful to make clear the structure of the wide resonance θ(1720),de-termine masses、widths、spins and other important properties of the two resonance states,for example G(1590) and f ₂(1720),including therein and understand the two interesting states better.
