摘要：

The effect of high pressure on the electric field gradient (EFG) present at Cd111 impurity nuclei in sp host metals of Zn, In, -Sn, and Tl has been measured by the time-differential perturbed angular correlation technique. The pressure range was up to 40 kbar for Tl and up to 30 kbar for other hosts. The EFG decreases with pressure for Zn and Tl hosts and increases for Sn and In. In all hosts the rate of change of the EFG with volume (lnqlnV)ca,T is in agreement with systematics. The results are compared with calculations based on existing theoretical approaches. © 1979 The American Physical Society.
