Inequivalence of the Klein-Gordon and Kemmer Formulations ofKl3Decay

Abstract
We answer the criticism that was raised against our Kemmer Kl3 theory by exhibiting in explicit calculational detail the inequivalence of the Kemmer and Klein-Gordon formulations of Kl3 decay, taking care to clearly define "inequivalence." It is shown that our published results are correct as stated, including the prediction of a zero in the scalar form factor.
