Abstract

The first measurement of the elementary process mu(-)p --> nu(mu)n gamma is reported. A photon pair spectrometer was used to measure the partial branching ratio (2.10 +/- 0.22) x 10(-8) for photons of k > 60 MeV. The value of the weak pseudoscalar coupling constant determined from the partial branching ratio is g(p)(q(2) = -0.88m(mu)(2)) = (9.8 +/- 0.7 +/- 0.3) g(alpha)(0), where the first error is the quadrature sum of statistical and systematic uncertainties and the second error is due to the uncertainty in lambda(op), the decay rate of the ortho to para p mu p molecule. This value of g(p) is similar to 1.5 times the prediction of partial conservation of axial current and pion-pole dominance.
