ResumoDecays of the J/ψ (3.1) resonance into final states with two charged hadrons and two photons are investigated. Branching ratios for the decays J/ψ → ϱπ and J/ψ → γη′ are determined to be Г(J/ψ → pφ)Г(J/ψ → all) = (1.0± 0.2) ·10−2, Г(J/ψ → γη′)ГJ/ψ → all) = (2.0± 0.7) ·−3 Upper limits for the same decay modes of ψ′ (3.7) are also determined.
