摘要:
Nuclear quadrupole interaction parameters have been determined at 293 and 77 K at the site of 181Ta nuclei in anhydrous HfCl4 by the method of time-differential perturbed angular correlations. Measurements performed on the 133–482 keV γ–γ cascade in 181Ta following the β decay of 181Hf indicate that HfCl4 does not possess cubic symmetry as claimed by some researchers.
