Case Studies in Atomic Collision Physics by E. W. McDaniel,M. R. C. McDowell Pdf

Case Studies in Atomic Collision Physics II focuses on studies on the role of atomic collision processes in astrophysical plasmas, including ionic recombination, electron transport, and position scattering. The book first discusses three-body recombination of positive and negative ions, as well as introduction to ionic recombination, calculation of the recombination coefficient, ions recombining in their parent gas, and three-body recombination at moderate and high gas-densities. The manuscript also takes a look at precision measurements of electron transport coefficients and differential cross sections in electron impact ionization. The publication examines the interpretation of spectral intensities from laboratory and astrophysical plasmas, atomic processes in astrophysical plasmas, and polarized orbital approximations. Discussions focus on collision rate experiments, line spectrum, collisional excitation and ionization, polarized target wave function, and application to positron scattering and annihilation. The text also ponders on cross sections and electron affinities and the role of metastable particles in collision processes. The selection is a valuable source of data for physicists and readers interested in atomic collision.

Case Studies in Atomic Physics 4 by E McDaniel Pdf

Case Studies in Atomic Physics IV presents a collection of six case studies in atomic physics. The first study deals with the correspondence identities associated with the Coulomb potential: the Rutherford scattering identity, the Bohr-Sommerfeld identity, and the Fock identity. The second paper reviews advances in recombination. This is followed by a three-part study on relativistic self-consistent field (SCF) calculations. The first part considers relativistic SCF calculations in general, and in particular discusses different configurational averaging techniques and various statistical exchange approximations. The second part reviews the relativistic theory of hyperfine structure. The third part makes a number of comparisons between experimental results and values obtained in different SCF schemes, with exact as well as approximate exchange. The next case study on pseudopotentials compares the results of model potential and pseudopotential calculations. The final study reviews, on a kinetic basis, the behavior of low density ion swarms in a neutral gas.

Collisions of Electrons with Atoms and Molecules by G.F. Drukarev Pdf

This book is a short outline of the present state of the theory of electron collisions with atomic particles - atoms, molecules and ions. It is addressed to those who by nature of their work need detailed information about the cross sections of various processes of electron collisions with atomic particles: experimentalists working in plasma physics, optics, quantum electronics, atmospheric and space physics, 'etc. Some of the cross sections have been measured. But in many important cases the only source of information is theoretical calcu lation. The numerous theoretical papers dealing with electronic collision processes contain various approximations. The inter relation between them and the level of their accuracy is often diffi cult to understand without a systematic study of the theory of atomic collisions, not to mention that theoretical considerations are necessary for the consistent interpretation of experimental results. The main constituents of the book are: 1. General theory with special emphasis on the topics most impor tant for understanding and discussing electron collisions with atomic particles.

Theory of Slow Atomic Collisions by E.E. Nikitin,S.Y. Umanskii Pdf

The theory of atom-molecule collisions is one of the basic fields in chemi cal physics. Its most challenging part - the dynamics of chemical reactions - is as yet unresolved, but is developing very quickly. It is here a great help to have an analysis of those parts of collision theory which are already complete, a good example being the theory of atomic collisions in process es specific to chemical physics. It has long been observed that many notions of this theory can also be applied successfully to reactive and unreactive molecular collisions. More over, atomic collisions often represent a touchstone in testing approaches proposed for the solution of more complicated problems. Research on the theory of slow atomic collisions carried out at the Moscow Institute of Chemical Physics has been based on just these ideas. A general viewpoint concerning the setting up and representation of the theory came out of these studies, and appeared to be useful in studying complicated systems as well. It underlies the representation of the theory of slow atomic colli sions in this book.

Polarization, Alignment, and Orientation in Atomic Collisions by Nils Andersen,Klaus Bartschat Pdf

This book covers polarization, alignment, and orientation effects in atomic collisions induced by electron, heavy particle, or photon impact. The first part of the book presents introductory chapters on light and particle polarization, experimental and computational methods, and the density matrix and state multipole formalism. Examples and exercises are included. The second part of the book deals with case studies of electron impact and heavy particle excitation, electron transfer, impact ionization, and autoionization. A separate chapter on photo-induced processes by new-generation light sources has been added. The last chapter discusses related topics and applications. Part III includes examples of charge clouds and introductory summaries of selected seminal papers of tutorial value from the early history of the field (1925 – 1975). The book is a significant update to the previous (first) edition, particularly in experimental and computational methods, the inclusion of key results obtained during the past 15 years, and the extended coverage of photo-induced processes. It is intended as an introductory text for both experimental and theoretical students and researchers. It can be used as a textbook for graduate courses, as a primary source for special topics and seminar courses, and as a standard reference. The book is accompanied by electronically available copies of the full text of the key papers in Part III, as well as animations of theoretically predicted electron charge clouds and currents for some of the cases discussed in Part II.

Lectures on Ion-Atom Collisions by Jörg Eichler Pdf

Atomic collisions offer some unique opportunities to study atomic structure and reaction mechanisms in experiment and theory, especially for projectiles of high atomic number provided by modern accelerators. The book is meant as an introduction into the field and provides some basic theoretical understanding of the atomic processes occurring when a projectile hits another atom. It also furnishes the tools for a mathematical description, however, without going deeper into the technical details, which can be found in the literature given. With this aim, the focus is on reactions, in which only a single active electron participates. Collisional excitation, ionization and charge transfer are discussed for collision velocities ranging from slow to comparable to the speed of light. For the highest projectile velocities, energy can be converted into mass, so that electron-positron pairs are created. In addition to the systematic treatment, a theoretical section specializes on electron-electron correlations and three chapters are devoted to selected highlights bordering to surface science and to physics with antiprotons. * Simple access to the theory of collisions between ions and atoms * Systematic treatment of basic features needed for an understanding * Mathematical details are omitted and referred to references * In order to bear out the essential ideas most clearly, a single active electron is assumed in most cases * In selected examples, theoretical results are confronted with experiment * Discussion supported by a large number of illustrations * Selected highlights in borderline fields are presented

Applied Atomic Collision Physics by H.S.W. Massey Pdf

Applied Atomic Collision Physics, Volume 1: Atmospheric Physics and Chemistry focuses on the applications of atomic collision physics in atmospheric physics and chemistry. The emphasis is on the physics of the upper atmospheres of the earth and planets as well as astrophysics, including solar physics, the physics of planetary nebulae, and reactions in interstellar space. Comprised of 12 chapters, this volume begins with an overview of the structure of the earth's atmosphere and its environment in interplanetary space, along with the structure of the terrestrial atmosphere at middle latitudes. The discussion then turns to the photochemistry of the midlatitude ionosphere; the thermal balance in the thermosphere at middle latitudes; atomic collisions in the lower ionosphere at midlatitudes; and airglow and auroras. Subsequent chapters explore the high latitude ionosphere, the exosphere, and the magnetosphere; the ionospheres of the planets and other bodies of the solar system; atmospheric processes involved in the stratospheric ozone problem; and solar physics. The final two chapters are concerned with applications to the physics of planetary nebulae and interstellar space. This book will be of interest to physicists and chemists.
