Abstract：
By an amplitudes analysis of the KKπ system in the J/ψ radiative decay to the K⁺K^－π⁰ and the K⁰_SK^±π⁺ final states,we find that there is one 0^－+ resonance (M=1467±3MeV,Γ=89±6MeV) and two 1⁺⁺ resonances (M=1435±3MeV,Γ=59±5MeV; M=1497±2MeV,Γ=44±7MeV),which are consistent with the η(1440),the f₁(1420),and the f₁(1510).
