Abstract
It is shown, in the "elementary-particle" treatment, that, if the source to produce the background (g.s.) comes only from the cascade processes , the average polarization of the recoil (g.s.) produced by the direct polarized-muon capture can be extracted reliably from the observed angular distribution of the electrons in the subsequent beta decays of (g.s.). Using the recent data of Possoz et al, our result for the average polarization of the recoil (g.s.) from the direct polarized-muon capture is , which agrees very well with the prediction of the standard picture, namely, conservation of vector current, partial conservation of axial vector current, and absence of second-class axial currents.
