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 e+photon+neutrino+antineutrino to muon decays to e+neutrino+antineutrino is predicted to be about 0.0001 over this angular range. The total number of inner bremsstrahlung events observed was 1805=43, which is in agreement with an expected number of 1889=283. The data were found to be in accord with the predictions given by electromagnetic corrections applied to the weak interaction. (Author)
