Quantum chaos on ordered structures by scattering techniques: Application to low-energy electron diffraction

Instituto de Ciencia de Materiales de Madrid, Consejo Superior de Investigaciones Cient´ificas, Cantoblanco, E-28049 Madrid,Spain(February 1, 2008)We analyze statistical probability distributions of intensi-ties collected by diffraction techniques like Low-Energy Elec-tron Diffraction. A simple theoretical model based in hard-sphere potentials and LEED formalism is investigated for dif-ferent values of relevant parameters: energy, angle of inci-dence, muffin-tin potential radius, maximum spherical com-ponent l
