摘要

A low energy beam of spin polarized Li-8 has been used to study the behaviour of isolated Li-8 implanted into a 150 nm thick film of Al on an MgO substrate. The spin relaxation rate 1/T-1 and beta-NMR lineshape were measured as a function of temperature in a large magnetic field of 4.1 T. The resonances from different sites are unresolved due to the large nuclear dipolar interaction with the host Al-27 magnetic dipole moments. Nevertheless the temperature variation of the site averaged 1/T-1 and Knight shift show evidence for a transition between the octahedral O and substitutional S sites at about 150 K, as observed in other fcc metals.
