摘要：

The quadrupole hyperfine interaction of Cd-111 in the cubic C-form sesquioxides of Sc, Y, Dy and Yb has been investigated over the temperature range 295-850 K with perturbed angular correlation (PAC) spectroscopy. The Cd-111 probe nuclei were either produced in the EC-decay of In-111 or in the gamma-decay of the Cd-111 isomeric state and introduced via ion implantation into the oxide matrices. A simple scaling of the components of the electric field gradient with the lattice constant has been observed on both substitutional octahedral sites.
