Azimuthally-dependent X-ray absorption near edge structure for sulphur adsorbed on Nickel(100).
01 January 1986
The X-ray absorption near edge structure (XANES) for S atoms in a half-monolayer coverage on the (110) surface of nickel shows a strong azimuthal dependence, not previously reported for an atomic adsorbate. The near edge resonance is shown by calculations to be determined in a complicated way by several shells of neighbouring atoms, and is not simply dominated by sulphur-nickel near neighbour scattering.
