  Ratios of coupling constants for these decays are compared with q-qbar
predictions and Jaffe's 4-quark model. In both models, the predicted ratio
g^2(kappa -> K-pi)/ g^2(sigma -> pi-pi) is much too small. Also, for q-qbar,
the predicted ratio g^2(kappa -> K-eta ')/g^2(kappa -> K-pi) is much larger
than observed. Both models fail for g^2(fo -> KK)/g^2(a0 -> KK). This ratio
requires that fo has a dominant KK component. It arises naturally because the
fo pole lies very close to the KK threshold, giving its wave function a long KK
tail.
