Description
A possible way to extract the value for the γ parameter in the radiative pion decay is presented through the study of the decay process π+→e+e+e-ν. A particular kinematic configuration is suggested to select those events dominated by the structure-dependent contribution without having to perform the difficult measurement on particle polarizations, but retaining the favored picture from the study of a polarized electron in the radiative pion decay π-→e-nu-barγ. A specific positron spectrum is given for this particular configuration to serve as a tentative way of determining an exact value for γ between the existing two possible ones
