Measurements ofJ/ψdecays intoϕπ0,ϕη, andϕη′

Based on 5 . 8 × 10 7 J/ψ events collected with BESII at the Beijing Electron-Positron Collider (BEPC), the decay branching fractions of J/ψ → ωπ 0 , ωη , and ωη ′ are measured using different η and η ′ decay modes. The results are higher than previous measurements. The ωπ 0 electromagnetic form factor is also obtained.
