“…The two previous experiments, those of Blake et at. 17 and of Llewellyn and Steffen,18 both yielded values of KK and, consequently, of the particle parameter, of the opposite sign and of smaller magnitude than the present work (see Table I). In the former experiment, the polarization analysis was accomplished by Mott scattering through an instrument angle of 90°, with the normal to the scattering foil making a 45° angle with the nominal incident beam direction.…”

The degree of transverse polarization P^{6)-KK{V/C) sin0 of the iC-conversion , electrons following the beta decay of Au 198 has been measured with a view to the determination of the particle parameter bi, tt (E2). The experimental result was obtained using a lens spectrometer to focus the conversion electrons on a thin gold foil, and measuring the Mott-scattering asymmetry 5 of the counts in coincidence with those detected in a beta detector placed opposite the source at an angle 0 of 90° with the spectrometer axis. The measured asymmetry of 5= -0.044±0.013 yields a value of iCx =+0.43=1=0.17, with all instrumental corrections applied. Given the beta-decay angular correlation coefficient A\{0) known from beta circularly polarized gamma correlations, the particle parameter is found to be bi, u(E2)= -1.0=b0.4. This value, although in disagreement with previous measurements, agrees with the value calculated by Becker and Rose.
