The Field Gradient Tensor at the Metal Site in Hafnium Acetylacetonate

Abstract

Time differential perturbed angular correlation measurements (TDPAC) were performed on 181Ta in hafnium acetylacetonate, Hf(acac)4. The asymmetry parameter, quadrupole interaction frequency, and frequency distribution spread of sources of synthetic and irradiated Hf(acac)4 were measured. Evidence for the existence of two sites with different asymmetry parameters (Beraud et al.) was not found.
