Apparent Fractality Emerging from Models of Random Distributions
Daniel A. Hamburger, Ofer Biham, David Avnir
The fractal properties of models of randomly placed -dimensional spheres (=1,2,3) are studied using standard techniques for calculating fractal dimensions in empirical data (…
He Scattering from Compact Clusters and from Diffusion-Limited Aggregates on Surfaces: Observable Signatures of Structure
Daniel A. Hamburger, A. Tamar Yinnon, Itshak Farbman +2
The angular intensity distribution of He beams scattered from compact clusters and from diffusion limited aggregates, epitaxially grown on metal surfaces, is investigated theoretic…
Optical Theorem and the Inversion of Cross Section Data for Atom Scattering from Defects on Surfaces
D. A. Hamburger, R. B. Gerber
The information content and properties of the cross section for atom scattering from a defect on a flat surface are investigated. Using the Sudden approximation, a simple expressio…
Fractal Dimension of Disordered Submonolayers: Determination from He Scattering Data
D. A. Hamburger, A. T. Yinnon, R. B. Gerber
We propose a novel method to measure the fractal dimension of a submonolayer metal adatom system grown under conditions of limited diffusivity on a surface. The method is based on…
