Abstract

We have re-examined the surface geometry of Ni(110)-c(2 x 2)-S using SEXAFS. Data out to an electron wavevector of 9 Å^-1 are analysed with a new code to assess the influence of multiple scattering. The first-shell S-Ni distance is determined to be 2.20±0.02 Å with the next-nearest neighbour distance being 2.29±0.02 Å, giving a top-layer Ni expansion of 14±3% relative to the bulk. The influence of multiple scattering is sufficiently small not to modify these values.
