Based on 5.8×107J/ψ events detected in BESII, the branching fractions of J/ψ→ϕη and ϕη′ are measured for different η and η′ decay modes. The results are significantly higher than previous measurements. An upper limit on B(J/ψ→ϕπ0) is also obtained.3 MoreReceived 15 October 2004DOI:https://doi.org/10.1103/PhysRevD.71.032003©2005 American Physical Society
