Abstract: (APS)

Branching ratios of Jψ decays into ωπ0, ωη, ωη′, ρη, ρη′, φη, φη′, and K*(892)K¯+charge conjugate are measured from the 8.6 × 106 Jψ's produced by the DM2 experiment at the Orsay e+e− storage ring DCI. The η and η′ mesons are found consistent with a qq¯ structure and a mixing angle θP=(−19.1±1.4)°.
