Description
Radioactive 111In+ ions were implanted into an α-Al2O3 single crystal. The hyperfine parameters of 111Cd at substitutional Al lattice sites were identified by measuring the perturbed angular correlation for different sample orientations. The electric field gradient Vzz = 1.04(17).1022 V/m2 was obtained from the quadrupole coupling constant. This result is compared with the efg values of 27Al in α-alumina and 111Cd in α-Fe2O3, which also has the corundum structure. Two additional fractions with broad frequency distributions were observed, one of which is attributed to 111Cd atoms in a strongly distorted Al2O3-lattice
