Abstract:

A measurement of inner bremsstrahlung in muon decay was made using spark chambers, scintillators and fast oscilloscopes. The electron range distribution in graphite and the absolute rates were determined for electrongamma-ray angles between 130 and 180 deg. For the electron and gamma-ray energies studied, the branching ratio of muon decays to ephotonneutrinoantineutrino to muon decays to eneutrinoantineutrino is predicted to be about 0.0001 over this angular range. The total number of inner bremsstrahlung events observed was 180543, which is in agreement with an expected number of 1889283. The data were found to be in accord with the predictions given by electromagnetic corrections applied to the weak interaction. Author
