Abstract：
Based on 7.8×10⁶ J/ψ events collected by BES experiment,J/ψ radiative decay J/ψ→γγV(ρ,φ) have been studied. The η(1430) resonance has been observed in these two channels respectively. Its mass,width and branching ratio are 1431±17MeV,88±28MeV,and Br(J/ψ→γη(1430)) Br(η(1430)→γρ)=(1.1±0.5±0.3)×10^－4 from J/ψ→γγρ mode,1424±15MeV,73±58MeV,and Br(J/ψ→γη(1430))Br(η(1430)→γφ)=(2.0±1.0±0.6)×10^－4 from J/ψ→γγφ mode.
