This new book edited by R Janev covers in 16 chapters almost all important atomic and molecular collision processes of relevance for the modelling and diagnostics of fusion edge plasmas. These processes include excitation, ionization of atoms and molecules by electrons, as well as electron - ion recombination processes and low-energy charge exchange collisions of impurity ions with neutral atoms. In addition, a chapter about the spectroscopic characteristics of plasma edge constituents is included. Each chapter deals with a specific type of collision process and comprises contributions from specialists in the respective fields. The book contains contributions from 27 authors. The primary purpose of the book is to provide the fusion plasma researcher with a source of critically assessed information on atomic and molecular collision processes. Many chapters give a basic introduction to the most commonly applied experimental and theoretical methods of how presented collision data are gained. Physical mechanisms of collision processes are described briefly on a rather fundamental level. Very helpful for a reader who is looking for more detailed information on a specific collision process are the comprehensive lists of references at the end of each chapter. Atomic data, such as cross sections, are represented by figures, tables and often (most helpful for quick and convenient application) by fitting parameters to analytic formulae. This book has to be regarded as an excellent review of the present day status of available data for low-energy collision processes between electrons, ions, atoms and molecules. Although this book is intended mainly for fusion plasma researchers, it might also be of interest for students and scientists working in atomic collision physics who are looking for an overview of this field.
