N2 - The octet-singlet mixing angle θp in the pseudoscalar meson nonet is deduced from the rich set of accurate data on J/ψ decays into a vector and a pseudoscalar meson. Corrections due to non-ideal ω-φ mixing have been included for the first time and turn out to be crucial to find θp = -16.9° ± 1.7°, which is appreciably less negative than previous results coming from similar analyses. © 1997 Elsevier Science B.V.
