These quantum numbers for f0 have recently been confirmed in several experiments, see, for example,L. Sodickson, M. Wahlig, I. Mannelli, D. Frisch andO. Fackler:Phys. Rev. Lett.,12, 485 (1964).

J=spin,P=space parity,X=dimension ofSU 3 representation,c=charge conjugation parity. The charge conjugation properties of the supermultiplets can readily be seen from the symmetry properties of the C.-G. coefficients tabulated, for example, byJ. J. de Swart:Rev. Mod. Phys.,35, 916 (1963). In de Swart’s notation we define charge conjugation parityc=±1 byCΨ μν =c(−1)I 2 +Y/2Ψ μ−ν .
M. Gell-Mann, D. H. Sharp andW. G. Wagner:Phys. Rev. Lett.,8, 263 (1962). We used a width of ω ∼ 7 MeV to estimate the coupling of ωρπ. Then using the fact that ϕ → ρ+π, and a mixing angle of 30°, we obtain the coupling strength of the pure octet member ϕ0. In our notation,G 22 /G 21 ∼ 2.6.
