Abstract :
Employing β-NMR on 8Li adsorbed on Ru(0 0 1) the local (at the Li nucleus) density of states at the Fermi energy has been determined as function of Li coverage. It is independent of coverage below 0.2 monolayer (ML) and saturates at a twice as large plateau value beyond 1 ML. Calculations employing all electron density functional theory reproduce qualitatively the trend of the data. At low and high coverages, agreement between theory and experiment is almost quantitative. In addition, new terrace diffusion parameters for Li on Ru(0 0 1) have been obtained.
