Phys. Rev. Lett. 46, 1469–1472 (1981)Electron-Energy-Loss Spectroscopy and Oxygen Overlayers on the Ni(100) SurfaceReceived 19 January 1981; published in the issue dated 1 June 1981 We present an analysis of the electron-energy-loss spectra produced by dipole scattering from lattice vibrations of the p(2×2) and c(2×2) oxygen overlayer on the Ni(100) surface. We conclude that the distance between the oxygen layer and the Ni surface is very much smaller for the c(2×2) overlayer than for the p(2×2), in accord with a recent suggestion by Upton and Goddard. © 1981 The American Physical Society URL:
