摘要: The branching ratio relative to ordinary muon capture and the photon asymmetry muon-spin direction were measured for radiative in /sup 40/Ca. For approx. 1200 events, partial is R/sub k>/sub 57/MeV/ = (21.1 +- 1.4) x 10/sup -6/, k > 63.5 MeV +0.90 0.50. A fit of spectrum theory Rood, Yano, Yano gives value g/sub p//sup ..mu../ (6.5 1.6) A/ pseudoscalar-coupling constants. These results are disagreement with earlier experiments.
