Abstract
Predictions for the coupling, the pion charge radius , the dependence of the pion decay constant near , and the ratio describing radiative pion decay are obtained in the context of two related models: the constituent-quark model and a baryon-loop model with flavors. All these models lead to two relations among the four above-mentioned parameters, which are satisfied by the data. A sort of equivalence or duality for the two models is observed, particularly for .
