This is a comprehensive text for a course on non-relativistic nuclear reactions. The main formalisms used to describe nuclear reactions are explained clearly and coherently, and the reader is led from basic laws to the final formulae used to calculate measurable quantities. Combining a thorough theoretical approach with applications to recent experimental results, this text covers all main topics including potential scattering, formal reaction theory, the theory of the optical model, direct and compound reactions, fusion, deep inelastic collisions, and induced fission. Lecturers, graduate students, and researchers in nuclear and atomic physics will find this a useful textbook and reference work.
