Description
We discuss two questions that arise from the Low theorem for spin 1/2 particles when different basic set of form factors are chosen in the non-radiative amplitude. At first glance, it seems as if this theorem were not independent of the choice of form factors. We show that one is really free to choose whatever basic set, except that in intermediate steps of the calculation of the Low amplitude one looses this freedom and one must instead follow a careful procedure (Author)
