  The form factor for the anomalous process gamma pi^+ -> pi^+ pi^0, which is
presently being measured at CEBAF, is calculated in the Schwinger-Dyson
approach in conjunction with an impulse approximation. The form factors
obtained by us are compared with the ones predicted by the simple constituent
quark loop model, vector meson dominance and chiral perturbation theory, as
well as the scarce already available data.
