Summary
We study a vector dominance model which predicts a fairly large number of currently interesting decay amplitudes of the types S -> γγ, V -> Sγ and S -> Vγ, where S and V denote scalar and vector mesons, in terms of three parameters. As an application we first use our approach to obtain the usual puzzling result Γ(φ -> f₀γ)/Γ(φ -> a₀°γ)≈< 1 rather than the observed value of about 3. The model makes it easy to test in detail a recent proposal to solve this puzzle by including the isospin violating a₀°-f₀ mixing and we find that it seems successful.
