Fractal Analysis of Protein Potential Energy Landscapes
D. A. Lidar, D. Thirumalai, R. Elber +1
The fractal properties of the total potential energy V as a function of time t are studied for a number of systems, including realistic models of proteins (PPT, BPTI and myoglobin)…
He Scattering from Random Adsorbates, Disordered Compact Islands and Fractal Submonolayers: Intensity Manifestations of Surface Disorder
A. T. Yinnon, D. A. Hamburger, I. Farbman +4
A theoretical study is made on He scattering from three fundamental classes of disordered ad-layers: (a) Translationally random adsorbates, (b) disordered compact islands and (c) f…
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…
