It most certainly is not wrong, and here is why not.
Fermi Theory of Beta Decay
In 1930, Wolfgang Pauli postulated the existence of the
neutrino to explain the continuous
distribution of energy of the electrons emitted in
beta decay. Only with the emission of a third particle could momentum and energy be
conserved. By 1934, Enrico Fermi had developed a theory of beta decay to include the neutrino, presumed to be massless as well as chargeless.
Treating the beta decay as a transition that depended upon the strength of coupling between the initial and final states, Fermi developed a relationship which is now referred to as
Fermi's Golden Rule:
Straightforward in concept, Fermi's Golden Rule says that the transition rate is proportional to the strength of the coupling between the initial and final states factored by the density of final states available to the system. But
the nature of the interaction which led to beta decay was unknown in Fermi's time (the weak interaction). It took some 20 years of work (Krane) to work out a detailed model which fit the observations.

Now, please dispense of saying things that are not true, which have been show to you many times just exactly how untrue you accusations concerning Fermis weak force theory. His theory was not wrong. The only problem was that he could not explain what he observed, as described above. Furthermore, this only applies to beta decay. Your accusations are completely unwarranted and completely false.
