The amplitude for the anomalous transitions gamma pi(+) -> pi(0) pi(+) isanalyzed within Chiral Perturbation Theory including electromagneticinteractions. The presence of a t-channel one-photon exchange contributioninduces sizeable e^2 corrections which enhance the cross-section in thethreshold region and bring the theoretical prediction into agreement withavailable data. In the case of the crossed reaction gamma pi(0) -> pi(+) pi(-),the same contribution appears in the s-channel and its effects are small.Comment: 16 pages, 4 figures, fixed two typos, no change
