| dc.description | The nuclear quadrupole interaction at substitutional Ta atoms in the alloy system Hf<sub>x</sub>Zr<sub>1-x</sub> has been investigated over the entire range of composition by time differential perturbed angular correlations (TDPAC). Source configurations investigated include oriented and randomised single crystals as well as textured, cold-worked and random polycrystals, all at room temperature. For both pure Zr and pure Hf, a pure electric quadrupole interaction is found of magnitude nu <sub>Q</sub>=eQV<sub>zz</sub>/h=303.9(15) MHz and 311.01(11) MHz respectively, which exhibits no electric field gradient (EFG) asymmetry and negligible damping due to finite distribution of the EFG strength. As increasing amounts of impurity are added at either end of the phase diagram, a two-component TDPAC pattern becomes evident: in addition to the undamped pure-metal spin rotation, a second component, exhibiting both damping and asymmetry, is seen at a somewhat higher frequency than that of either pure metal. The fraction of this second component, its frequency, the degree of asymmetry, and the distribution width of the EFG all increase monotonically with increasing impurity concentration. |
