We have measured the branching ratio of the radiative decay pi --> mu nu gamma. The energies of the gamma-ray and of the muon were both measured and the Dalitz-plot distribution of the decay was obtained. The data agree well with the theoretical prediction (QED internal bremsstrahlung) down to a gamma-ray energy of 1 MeV. The discrepancy reported in a previous experiment is not confirmed.

Abstract
We have measured the branching ratio of the radiative decay pi --> mu nu gamma. The energies of the gamma-ray and of the muon were both measured and the Dalitz-plot distribution of the decay was obtained. The data agree well with the theoretical prediction (QED internal bremsstrahlung) down to a gamma-ray energy of 1 MeV. The discrepancy reported in a previous experiment is not confirmed.
