The asymmetry in beta emission from polarized Ar35 nuclei and the nuclear magnetic moment of Ar35 have been determined by an atomic-beam method used previously for similar measurements on Ne19. The results are: for the asymmetry parameter, A=+0.16±0.04; and for the nuclear moment, μ=+0.632±0.002 nm. The experimental value of A is used to obtain the Gamow-Teller beta-decay matrix element: σ=0.10±0.05. This result is consistent with the measured ft value and electron-neutrino angular correlation coefficient in the decay of Ar35. The results are also consistent with a rotational model of Ar35 using a deformation parameter close to that of Cl35.
