The photon asymmetry (α γ ) and partial branching ratio above 57 MeV ( R k > 57) have been measured for radiative muon capture on 40 Ca in order to determine the magnitude of the induced-pseudoscalar coupling constant, g p . Based on 2500 events a value of α γ = 1.32 +0.57 −0.47 is obtained from a fit to the photon time spectrum; this implies a value for g p <5.2 g A . For the first time the asymmetry signal is clearly visible and unconstrained multi-parameter fits reproduce the parameters obtained from the decay electron spectrum. The present results are discussed and compared in detail with previous results.
