Nuclear orientation of the rare-earth system\(^{160} Tb\underline {Tb} \) (sc)

We report precision nuclear orientation measurements on a bulk160TbTb single crystal sample. The results of these experiments allow us to determine the hyperfine parameters for this system, as well as precise multipole mixing ratios for 22 gamma rays from the160Dy daughter nucleus. Various methods of extracting the mixing ratios will be compared.
