The electric quadrupole interaction at Cd and Ta impurity nuclei implanted in trace amounts in a titanium host lattice has been measured as a function of temperature by means of the time‐differential perturbed angular correlation technique. The results show a striking difference in the temperature dependences for the two impurity species. This implies that, in addition to the previously observed temperature dependence arising from lattice expansion and conduction electron redistribution of the host, there exist significant local temperature dependent effects associated with the specific characteristics of the impurity.
