Results from the analysis of five radiative J/ψ decays are presented. In J/ψ→γK K̄, the f′(1515), θ(1720), and a new state, the ξ(2200), are observed in the K K̄ mass spectrum. In the double radiative decay J/ψ→γX;X→γp 0, evidence is presented for structure near 1.4 GeV. Finally, in the three SU(3) related decays J/ψ→γρ→ ρ0, J/ψ→γρ+ρ−, and J/ψ→γωω, structure is observed near 1.7 GeV. Analysis of the decay angular distributions in these three modes indicates that even spin and odd parity predominate in this mass region.
