The angular correlation of the (1380 kev) - (80 kev) gamma - gamma cascade in the decay of 27 hr Ho/sup 166/ was measured in an external magnetic field of 13.550 G. The observed rotation yields for the nuclear g-factor of the 80-kev 2+ rotational state was g/sub R/ = +0.260 plus or minus 0.034. A paramagnetic correction factor of beta = 8.36 (B/sub eff/ = beta /sub ext/) was applied in the calculation of this value. There was a strong attenuation of the (1380 kev) - (80 kev) angular correlation by internal fields. The attenuation factors for a liquid source of HoCl/sub 3/ in aqueous solution were determined as G/sub 2/ = 0.80 plus or minus 0.08 and G/sub 4/ = 0.56 plus or minus 0.04. A measurement of the (1380 kev)--(80 kev) angular correlation for different delays showed agreement with a time dependent attenuation A/sub k/(t) = A/sub k/ (0) e/sup -/ /sup lambda /k /sup t/, where the lambda /sub k/ are lambda /sub 2/ =0.09 x 10/sup 9/ sec/sup -1/ and lambda /sub 4/ = 0.30 x 10 /sup 9/ sec/sup -1/. The ratio of lambda /sub 4// lambda /sub 2/ suggests that the attenuation is caused mainly by magnetic interaction between the 4f electron shell and the magnetic moment of the nucleus. The spin relaxation time for the 4f electron shell was calculated as /sub /J = (3.4 plus or minus 0.9) x 10/ sup -13/ sec. (auth)
