  The anomalous processes, \gamma \to 3 \pi and \gamma \pi \to \pi\pi, are
investigated within the Dyson-Schwinger framework using the rainbow-ladder
approximation. Calculations reveal that a complete set of ladder diagrams
beyond the impulse approximation are necessary to reproduce the fundamental
low-energy theorem for the anomalous form factor. Higher momentum calculations
also agree with the limited form factor data and exhibit the same resonance
behavior as the phenomenological vector meson dominance model.
