The effects of electromagnetic-production processes due to two-photon exchange in nucleus-nucleus collisions are discussed. Feynman diagrams for two-photon exchange are evaluated using quantum electrodynamics. The total cross section and stopping power for projectile and target nuclei of identical charge are found to be significant for heavy nuclei above a few GeV per nucleon-incident energy.

Until the publication of the first edition of Introduction to Nuclear Reactions in 2004, an introductory reference on nuclear reactions had been unavailable. Now, fully updated throughout, this second edition continues to provide an authoritative overview of nuclear reactions. It discusses the main formalisms, ranging from basic laws to the final formulae used in academic research to calculate measurable quantities. Well known in their fields, the authors begin with a basic introduction to elements of scattering theory followed by a study of its applications to specific nuclear reactions. Early chapters give a framework of compound nucleus formation and its decay, fusion, fission, and direct reactions, that can be easily understood by the novice. These chapters also serve as prototypes for applications of the underlying physical ideas presented in previous chapters. The largest section of the book comprises the physical models that have been developed to account for the various aspects of nuclear reaction phenomena, including reactions in stellar environments, cosmic rays, and during the big bang. The final chapters survey applications of the eikonal wavefunction and of nuclear transport equations to nuclear reactions at high energies. By combining a thorough theoretical approach with applications to recent experimental data, Introduction to Nuclear Reactions helps you understand the results of experimental measurements rather than describe how they are made. A clear treatment of the topics and coherent organization make this information understandable to students and professionals with a solid foundation in physics as well as to those with a more general science and technology background. Features: Analyses in detail different models of the nucleus and discusses their interrelations. Fully updated throughout, with new sections and additional discussions on stellar evolution, big bang nucleosynthesis, neutron stars and relativistic heavy ion collisions. Discusses the latest developments in nuclear reaction theory and experiments and explores both direct reaction theories and heavy ion reactions, which are newly important to nuclear physics in reactions with rare nuclear isotopes.
