Lectures On Ion Atom Collisions

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

Excerpt from Lectures on Ion-Atom Collisions This report contains lectures delivered at the Joint Institute for Laboratory Astrophysics, University of Colorado, during September, 1962. The material of the first four is largely taken from recent books by D. R. Bates, and was presented for pedagogic purposes only. It does not purport, in any sense, to be a record of original work by the author. Any new material is confined to the last two lectures.

This book is based upon a part of the invited and contributing talks at the 25th International Symposium on Ion-Atom Collisions, ISIAC (biennial), held on July 23-25, 2017 in Palm Cove, Queensland, Australia. To aid the general reader, all the authors tried to present their chapters in the context of the development of the addressed particular themes and the underlying major ideas and intricacies. Some chapters contain new results that have not been previously published elsewhere. Whenever possible, the authors made their attempts to connect the basic research in atomic and molecular collision physics with some important applications in other branches of physics as well as across the physics borders. It is hoped that the material presented in this book will be interesting and useful to the beginners and specialists alike. The contents and expositions are deemed to be helpful to the beginners in assessing the potential overlap of some of the presented material with their own research themes and this might provide motivations for possible further upgrades. Likewise, specialists could take advantage of these reviews to see where the addressed themes were and where they are going, in order to acknowledge the fruits of the efforts made thus far and actively contribute to tailoring the directions of future research. Overall, this book is truly interdisciplinary. It judiciously combines experiments and theories within particle collision physics on atomic and molecular levels. It presents state-of-the-art fundamental research in this field. It addresses the possibilities for significant and versatile applications outside standard atomic and molecular collision physics ranging from astrophysics, surface as well as cluster physics/chemistry, hadron therapy in medicine and to the chemical industry. It is then, as Volume 2, fully in the spirit of the 'Aims and Scope' of this book series by reference to its 'Mission Statement'.

These proceedings give fundamental information on the collision mechanisms of ions and atoms at relatively high energies and on their highly excited atomic states. The information derived from such studies can often be applied in other fields such as material analysis, dosimetry, the study of the upper atmosphere and controlled fusion. Phenomena involving the classical ion-atom collision fields, impact parameter dependences, quasimolecular and electron correlation effects, coherence phenomena, the electron and photon spectroscopy of highly charged projectile and recoil ions, the loss and capture of electrons, molecular and solid state effects, and different aspects of instrumentation are all discussed in this volume.
