During the last two decades the theory of ion-atom collisons, and particularly of charge-exchange reactions has advanced rapidly to the point where existing texts are no longer suitable as an introduction to the subject. This book aims to remedy the situation by providing an account of modern theoretical methods used to study the interaction of positive ions with atoms (or ions), concentrating particularly on charge exchange reactions. These reactions cannot be studied in isolation, and it is necessary to consider, to some extent, the whole range of ion-atom collisions leading to elastic scattering, excitation, and ionization. The material is presented at a level suitable for beginning research students and is self-contained, but assumes a knowledge of undergraduate quantum mechanics and atomic physics. It should also be useful for experimentalists who wish to assess the status of theoretical treatments of those collision processes in which they are interested.

Case Studies in Atomic Physics III focuses on case studies on atomic and molecular physics, including atomic collisions, transport properties of electrons, ions, molecules, and photons, interaction potentials, spectroscopy, and surface phenomena. The selection first discusses detailed balancing in the time-dependent impact parameter method, as well as time-reversal in the impact parameter method and coupled state approximation. The text also examines the mechanisms of electron production in ion. Topics include measurement of doubly differential cross sections and electron spectra, direct Coulomb ionization, autoionization and Auger effect, charge transfer to continuum states, and electron promotion. The book takes a look at the production of inner-shell vacancies in heavy ion-atom collisions and hyperfine and Zeeman studies of metastable atomic states by atomic-beam magnetic-resonance. Topics include molecular orbital model, experimental considerations, and theoretical considerations and interpretation of experimental results. The manuscript also evaluates the coupled integral-equation approach to nonrelativistic three-body systems with applications to atomic problems, including kinematic theory of three-body system, reduction of the coupled equations, and application to atomic problems. The selection is a dependable reference for readers interested in atomic and molecular physics.
