Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1995-03-22 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interface phenomena are most fascinating because of the mixing of different scales and the interference of diverse physical processes. This makes it necessary to use different levels of description: microscopic, kinetic, and gas-dynamical. A unified quasiclassical approach is used to answer practical questions dealing with inelastic gas-surface scattering, the kinetics of adsorption layers, the evolution of inhomogeneities and defects at the surface, the Knudsen layer, the development of boundary conditions on the kinetic and gas-dynamical levels, the determination of exchange and slip coefficients, and so on.

Available in PDF, EPUB and Kindle. Book excerpt: Helium and molecular hydrogen scattering from copper is calculated to examine general features of scattering for these systems, especially the quantum mechanics of the scattering process, both for the motion of the particle and the excitations of the lattice. These calculations use an interaction potential chosen to simplify the numerical calculation while retaining the essential physics of the interaction. The scattering calculations show that these approximations quantitatively reproduce experimental results. The scattering probabilities are shown to depend on details of the system like the well depth and the steepness of the potential and assumptions are made to simplify the interaction potential. H2 and D2 inelastic scattering and trapping probabilities show strong enhancement by selecti adsorption resonances and overall changes in scattering intensities due to other more subtle effects of the rotational degrees of freedom. Temperature dependent HD scattering probabilities show the effect of inelastic scattering on rotationally inelastic scattering and selective adsorption resonances.

Available in PDF, EPUB and Kindle. Book excerpt: A method is presented for calculating elastic and inelastic scattering probabilities for light particles, such as helium and molecular hydrogen, scattering from surfaces with which they weakly interact. The method is a unitary one-phonon approximation in which the scattering probabilities are calculated from thermally averages amplitudes which are generated numerically. The thermal averaging procedure is more general than this application and could be applied to other systems with weak inelastic scattering. An approximation for the gas surface interaction potential is discussed that can greatly simplify calculations where it is applicable. Finally some preliminary results are presented using this method to study rotationally mediated selective adsorption resonances in HD scattering from copper.

Book excerpt: This research initiative deals with the interaction of neutral particle, electron, and optical beams with well-characterized single crystal surfaces. These studies are motivated by a desire to understand and control surface reactions, such as surface oxidation, the technological need to characterize the physical properties of thin films and surfaces, and the desire to understand how energy and momentum are exchanged at the surface of a material when it is subjected to gas-surface collisions, electron-surface collisions, optical illumination, or chemical reaction. Experiments aimed at determining the surface phonon dispersion relations for a variety of clean and adsorbate covered systems play a central role in this program. Such measurements are crucial for elucidating how the force constants at the surface differ from those characteristic of the bulk for a given material, and how adsorption of atomic and molecular species modify the force constants, and hence electron density distributions, at and in the vicinity of the surface. The experimental program utilizes two, now fully operational, scattering laboratories that were constructed with significant DoD funding. One of these is a high resolution (energy and momentum) neutral particle scattering apparatus which routinely carries out single phonon inelastic as well as diffractive scattering measurements. The other laboratory houses an inelastic electron scattering instrument which also produces momentum-resolved inelastic scattering data. The capabilities of these two facilities complement each other in many important and useful ways.

Available in PDF, EPUB and Kindle. Book excerpt: The focus of this excellent textbook is the topic of molecular reaction dynamics. The chapters are all written by internationally recognised researchers and, from the outset, the contributors are writing with the young scientist in mind. The easy to use, stand-alone, chapters make it of value to students, teachers, and researchers alike. Subjects covered range from the more traditional topics, such as potential energy surfaces, to more advanced and rapidly developing areas, such as femtochemistry and coherent control. The coverage of reaction dynamics is very broad, so many students studying chemical physics will find elements of this text interesting and useful. Tutorials in Molecular Reaction Dynamics includes extensive references to more advanced texts and research papers, and a series of 'Study Boxes' help readers grapple with the more difficult concepts. Each chapter is thoroughly cross-referenced, helping the reader to link concepts from different branches of the subject. Worked problems are included, and each chapter concludes with a selection of problems designed to test understanding of the subjects covered. Supplementary reading material, and worked solutions to the problems, are contained on a secure website.
