Abstract
The surface structure of Ni(110) has been determined by means of an r-factor comparison of experimental and calculated LEED intensity-energy spectra from two different crystals, for nine diffracted beams, in the energy range 60-360 eV at normal incidence. The surface structure is found to exhibit a damped, oscillatory relaxation of the surface interlayer spacings, with relaxations of Delta d1=-8.7%, Delta d2=+3.0% and Delta d3=-0.5% with respect to the bulk value. These results are discussed in the context of previous studies of the relaxation of metal surfaces.Keywords
