ABSTRACT
In any case, Wolfgang Pauli's hypothesis became widely known within the physics community despite its lack of publication. The first difficulty consists in the existence of the sharp upper limits of ß-spectra, which although not in direct contradiction to the hypothesis, still throws some weight on the side of the conservation laws. Pauli's neutron, or neutrino, solved the problem of the continuous energy spectrum and saved the conservation laws. If the neutrino was emitted along with the electron, then a unique electron energy was no longer required by the conservation laws. George Gamow believed that the Pauli hypothesis was better supported by the available evidence. He remarked on the difficulties faced by Niels Bohr's suggestion of energy nonconservation. In addition, the general shape of the observed energy spectra in ß decay was in agreement with the predictions of Enrico Fermi's theory.
