Abstract

We report detailed behaviour of low energy ⁸Li implanted near the surface of α- Al2O3 single crystal, as revealed by beta-detected NQR of ⁸Li. We find that the implanted ⁸Li occupies at least two sites with non-cubic symmetry in the Al2O3 lattice. In both sites the ⁸Li experiences axially symmetric electric field gradient, with the main principal axis along the c-crystallographic direction. The temperature and field dependence of the spin lattice relaxation of ⁸Li in α-Al2O3, indicate that the ⁸Li diffusion is negligible on the scale of its lifetime, 1.21 s.
