A system of spark chambers and scintillation counters has been used to observe the structure-dependent part of the radiative electronic decay of the positive pion: π<sup>+</sup> e<sup>+</sup> + ν + γ.Eleven events have been observed with a mean background of 2.6 ± 1.1. The value of the parameter γ as defined by Bludman and Young was found to be either 1 6 ± 0 7 or -3 1 ± 0.7.
