Abstract
As a consequence of the nonconservation of parity in beta decay, beta particles emitted in first-forbidden beta transitions exhibit a small degree of polarization transverse to their momentum. The direction of the transverse polarization is defined with respect to a plane which is introduced by observing the direction of emission of the beta particle and the direction of emission of a gamma ray following the beta transition. The degree of the transverse polarization parallel to the beta-gamma plane , and the degree of polarization perpendicular to the beta-gamma plane has been measured for . The beta polarization has been detected by means of the left-right asymmetry in a Mott scattering process for an average electron energy and for an angle between the beta momentum and the gamma direction. The results of the measurements, and , agree satisfactorily with the values calculated on the basis of the approximation from the anisotropy of the beta-gamma directional correlation.
