摘要：

We show that to first order in α, and with neglect of effects which vanish in the limit of zero lepton momenta, the theoretical ft value in 0 → 0 Fermi transitions is independent of Z. The only model-dependent feature of this argument is in the treatment of effects induced by the axial current. It is further shown that in higher order radiative corrections the power of Z cannot exceed the power of α; the leading term in the radiative correction to the ft value is therefore of order Z2α2. © 1969 The American Physical Society.
