Abstract
A Ge(Li)--Nal(T1) angular correlation system with a fast-slow electronic coincidence system was used to remeasure the directional angular correlation of the 71.66 - 249.69 keV cascade in 177Hf. After corrections for finite solid angles the anisotropy ratio of A = -0.162 ± 0.026 was obtained. The upper limit | δ | M2/E1 mixing ratio for the 71.66 keV transition was deduced. The results for angular correlation coefficients are A22 = -0.114 ± 0.018 and A44 = 0.
