	abstract = {We report detailed behaviour of low energy 8 Li implanted near the surface of α- Al 2 O 3 single crystal, as revealed by beta-detected NQR of 8 Li. We find that the implanted 8 Li occupies at least two sites with non-cubic symmetry in the Al 2 O 3 lattice. In both sites the 8 Li 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 8 Li in α-Al 2 O 3 , indicate that the 8 Li diffusion is negligible on the scale of its lifetime, 1.21 s.},
