Larmor Precession of the First Rotational Level of 181Ta

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.
