Dynamics of Gas-Surface Scattering


Book Description

Dynamics of Gas-Surface Scattering deals with the dynamics of scattering as inferred from known properties of gases and solids. This book discusses measurements of spatial distributions of scattered atomic and molecular streams, and of the energy and momentum which gas particles exchange at solid surfaces. It also considers two regimes of scattering, both of which are associated with a lower range of incident gas energies: the thermal and structure scattering regimes. Comprised of 10 chapters, this book opens with a brief historical overview of the early experiments that investigated the dynamics of scattering of gases by surfaces. The discussion then turns to some elements of the kinetic theory of gases; intermodular potentials and interaction regimes; and classical-mechanical lattice models used in gas-surface scattering theory. The applications of molecular beams to the study of gas-surface scattering phenomena are also described. The remaining chapters focus on experiments and theories on scattering of molecular streams by surfaces of solids, with emphasis on thermal and structure regimes of inelastic scattering; quantum theory of gas-surface scattering; and quantum mechanical scattering phenomena. This text concludes with an analysis of energy exchange processes that may occur when a solid surface is completely immersed in a still gas. This monograph will be a valuable resource for students and practitioners of physics, chemistry, and applied mathematics.
















Surface Scattering and Other Surface Phenomena


Book Description

This Grant permitted the initiation of a theoretical solid state physics group in the University of Virginia, which now consists of about seven faculty members. The program of Surface Physics which it was supposed to develop has really just started, but in a very promising way. Substantial and important contributions have been made to the theories of: magnetic and superconducting properties of solids; resonance elastic and inelastic scattering of light atoms from solid surfaces; and thermodynamics of surfaces. Work has progressed also on two other topics, although no substantial success has been achieved yet - namely, establishment of a bridge between quantum-mechanical theories of scattering of light gases from solid surfaces and the corresponding classical-mechanical theories for heavy gases; and, motion of defects in crystal lattices.

Fundamentals of Gas-Surface Interactions


Book Description

Fundamentals of Gas–Surface Interactions presents the study of the surface itself and the study of the gas phase partner of the interaction in which physical or chemical transformation of the gas resulted from that interaction. This book discusses the study of the energy and momentum exchanges resulting from the gas–solid physical interaction in which either gas or solid phase properties can be measured. Organized into three parts encompassing 33 chapters, this book begins with an overview of the different sensitive physical methods for the study of surface topography, surface defects, and surface irregularities to an accuracy of a few Angstroms. This text then reviews the adsorption at very low coverage that has yielded to equilibrium analysis. Other chapters consider the measurement of surface area by adsorption and optical techniques. The final chapter deals with scattering processes including momentum and energy transfer. This book is a valuable resource for engineers.
