Interpretation of inelastic scattering of He from Cu surfaces in the anticorrugated potential model

In this paper we demonstrate that inclusion of the anticorrugation effects in the pseudopotential describing the dynamic interaction of neutral He atoms with phonons of Cu(1 1 1) and Cu(1 0 0) surfaces can resolve the long standing discrepancy between the inelastic scattering intensities inferred from HAS-TOF and from the electron energy loss spectroscopy data.
