The authors decided to write this book when they could find no other texts for a course on non-relativistic nuclear reactions. It combines a thorough theoretical approach with applications to recent experimental results. 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. Topics include quantal and semi-classical potential scattering; the formal theory of nuclear reactions, including the theory of the optical model; and direct reactions and coupled-channel systems. Also included are compound nucleus reactions and fusion, dissipation fluctuations in deep-inelastic collisions, fusion, and heavy-ion induced fission. The book will be welcomed by graduate students and researchers in nuclear and atomic physics.
