Radiative decays of light pseudoscalar mesons have recieved more and more theoretical and experimental attention in recent years. In this paper a study of the decay ..pi../sup +/..-->..e/sup +/..nu gamma.. is given. The amplitude splits into two pieces: one corresponding to internal bremsstrahlung and the other to the so-called structural part. QCD sum rules are used to calculate the axial form factor of the structural part of the decay amplitude..(AIP)
