[en] The branching ratios and the ratios of the helicity amplitudes (x and y) of the process J/PSI → γ + (Q/sup 2/Q-bar/sup 2/)/sub 2/++ → γ + VV have been calculated. The branching ratio of the process J/PSI → γ + (Q/sup 2/Q-bar/sup 2/)/sub 2/++ → γ + rho/sup 0/rho/sup 0/ is quite compatible with recent experimental data and it's x and y values are different from the ones measured in the process J/PSI → γ + Θ → γ + etaeta (KK-bar). The processes of J/PSI → γ + (Q/sup 2/Q-bar/sup 2/)/sub 2/++ → γ + ωω, K/sup */K-bar/sup */ have large branching ratios and should be found in J/PSI radiative decays. The branching ratio of J/PSI → γ +(s/sup 2/s-bar/sup 2/)/sub 2/++ → γ + phiphi is calculated to be smaller than that of J/PSI → γ + (Q/sup 2/Q-bar/sup 2/)/sub 2/++ → γ [ rho/sup 0/rho/sup 0/ by a factor of --25
