【 摘 要 】

We summarize some features of the vector meson dominance model which was recently proposed for studying radiative decays involving the scalar mesons. Using the experimental values of (Gamma)(a(sub 0) (yields) (gamma)(gamma)), (Gamma)(f(sub 0) (yields) (gamma)(gamma)) and (Gamma)((phi) (yields) a(sub 0) (gamma)) as inputs, we show that the model predicts a large hierarchy between (Gamma)(a(sub 0) (yields) (omega)(gamma)) and (Gamma)(a(sub 0) (yields) (rho)(gamma)) as well as between (Gamma)(f(sub 0) (yields) (omega)(gamma)) and (Gamma)(f(sub 0) (yields) (rho)(gamma)).
