Electric quadrupole interactions ofCd111nuclei in the cubic Ag lattice doped with Sn impurity

The electric quadrupole interactions produced by near-neighbor impurity atoms of Sn on ${}_{}{}^{111}{}_{}{}^{}\mathrm{Cd}$ probe nuclei in a cubic Ag lattice were studied by the time-differential perturbed angular correlation technique. The effects of concentration of the impurity and of temperature have been investigated. The results show the presence of a high-frequency interaction ${\omega }_h$ superimposed to a smeared out low frequency ${\omega }_l$. Both ${\omega }_h$ and ${\omega }_l$ increase with the impurity concentration, but the ratio $\frac{{\omega }_h}{{\omega }_l}$ is constant for all the concentrations.
