Klappentext This book provides an account of the calculation of the matrix elements of the magnetic interaction operator, extracting important, useful results from mathematical analysis. The authors give a complete theory of nonrelativistic magnetic neutron scattering with various tables listing nj symbols, fractional parentage coefficients, and various other quantities that arise naturally in the theory. Subsequently, the book takes account of the growing interest in magnetic photon scattering realized by synchrotron photon factories and contains an appropriate theory. While the treatment centers on scattering from atomic electrons, scattering from conduction electrons is also covered. Zusammenfassung The techniques of magnetic neutron and photon scattering provide information on the electronic properties of materials that is obtainable in no other way. With both techniques information on an atomic scale is obtained on the spatial and temporal developments of the spin and current densities which are fundamental quantities in a basic understanding of magnetic phenomena. To date most magnetic scattering studies have used neutron beams, and the use of photon beams is, relatively speaking, in its infancy.This book is the first monograph devoted to the theory required for a full interpretation of magnetic scattering experiments. It is designed to meet the needs of postgraduates and researchers new to the techniques. At the same time, the requirements of theoretical chemists and physicists are catered for through chapters that present the basic formalism in detail. Special features of the book include extensive tables of quantities that occur frequently in applications of theory, and a number of worked examples.
