Interatomic Potentials provides information pertinent to the fundamental aspects of the interaction between atoms. This book discusses the theory of interatomic forces or potentials, which deals with the complicated problem of many-body interactions.Organized into 10 chapters, this book begins with an overview of the physical principles behind a range of atomic interactions and show how they can be applied to some atomic problems. This text then examines some of the theories of the atom that employ various approximate methods to simplify the many-body problem and estimate it potential energy. Other chapters consider the application of computer techniques to atomic problems. This book discusses as well the general principles and the particular types of pair interactions based on the pseudopotential method. The final chapter deals with some applications of interatomic potentials.This book is a valuable resource for graduate students, research workers, and teachers. Atomic and solid state physicists will also find this book useful.
