摘要：

The time differential perturbed angular correlation technique was applied to study the electric quadrupole coupling of Cd-111 in the II-VI semiconductor CdS (20 K less-than-or-equal-to T less-than-or-equal-to 1000 K). Two kinds of sample preparation were used: implantation and diffusion. Obtained results for the regular lattice sites were independent of the preparation. The measured electric field gradient (EFG) was between 6.7 +/- 0.4 MHz and 9.1 +/- 0.2 MHz. Data were confirmed by point-charge calculations. Implantation however caused a second EFG (almost-equal-to 78 MHz) that was assigned to a defect due to the preceding irradiation.
