Application of simple kinematic predictions for the structural search in LEED

A simple computational model based on the kinematic scattering approach was tested for the ability to determine the surface structure of Ni(100), Ni(1 00)-c(2 x 2)-Na and Al(111), and the results were compared with those found by the complex dynamical analysis. Although to describe precisely the surf ace solid structures, the dynamical theory must be generally applied, the r ough treatment of the experimental data by this kinematic method gave us an useful estimation of the structural parameters. Additionally, a detailed s tatistical analysis of the structural parameters was carried out. (C) 1999 Published by Elsevier Science Ltd. All rights reserved.
