This book provides a comprehensive and up-to-date account of the field of low energy positrons and positronium within atomic and molecular physics. It begins with an introduction to the field, discussing the background to low energy positron beams, and then covers topics such as total scattering cross sections, elastic scattering, positronium formation, excitation and ionisation, annihilation and positronium interactions. Each chapter contains a blend of theory and experiment, giving a balanced treatment of all the topics. The book will be useful for graduate students and researchers in physics and chemistry. It is ideal for those wishing to gain rapid, in-depth knowledge of this unique branch of atomic physics.

"...clearly written...The book's completeness on its princiapl topics, including references of about 800 of the original works, is exhaustive enough that I shall finally be able to discard my extensive reprint collection...I recommend this book. Because of its good writing, its reliability, its choice of material, and its excellent degree of coverage, it is a good text for beginning annihilators and a handy reference for their professors."

"Positron Physics is a real textbook, though without exercises. Its unifying viewpoint and beautiful format as a Cambridge University Press monograph should be an inspiration for others...I recommed this book. Because of its good writing, its reliability, its choice of material, and its excellent degree of coverage, it is a good text for beginning annihilators and a handy reference for their professors."
