Abstract
Perturbed angular correlation measurements have been made on the decay of 181Hf implanted in iron. The average integral rotation angle for the 136 keV 9/2+ state of 181Ta is ωτ = 0.051 ± 0.004 rad. For the internal field on Ta in iron of 640 kOe, this gives a nuclear g factor of 0.27 ± 0.04. Alternative explanations of the small rotation are discussed. The E2/M1 mixing ratio of the 136 keV transition was found to be δ = −0.44 ± 0.04.Keywords
