Abstract:
Fourier transform nuclear magnetic resonance at single crystal surfaces is described. The adsorption of 6Li on Ru(001) is investigated by newly developed techniques utilizing atomic beam sample preparation and optical detection of the NMR signal on desorbing atoms (laser induced fluorescence) or ions (beamfoil spectroscopy). In complete analogy to magnetically detected NMR, the transverse magnetisation is coherently recorded. This allows pulse NMR to be applied to surface problems.
