Abstract
The asymmetry in beta emission from polarized nuclei and the nuclear magnetic moment of have been determined by an atomic-beam method used previously for similar measurements on . The results are: for the asymmetry parameter, ; and for the nuclear moment, nm. The experimental value of is used to obtain the Gamow-Teller beta-decay matrix element: . This result is consistent with the measured value and electron-neutrino angular correlation coefficient in the decay of . The results are also consistent with a rotational model of using a deformation parameter close to that of .
