The Scattering of He, Ne, AR, and Xe from the (111) Plane of Ni; Comparison with Ag (111) and au (111)

摘要

The scattering of He, Ne, Ar, and Xe from Ni(111) is examined as a function of beam temperature and angle of incidence. The results are consistent within themselves when considered in light of earlier data and the predictions from the simplified 'cube' models. However, a careful comparison of the present data with earlier Au(111) and Ag(111) data shows trends that may be related to the lattice properties of the solid and which demonstrate that a simple description of the solid in terms of mass and heat of physical adsorption is inadequate.
