Application of quantum mechanics in physics and chemistry often entails manipulation and evaluation of sums and products of coupling coefficients for the theory of angular momentum. Challenges encountered in such work can be tamed by graphical techniques that provide both the insight and analytical power. The book is the first step-by-step exposition of a graphical method grounded in established work. Copious exercises recover standard results but demonstrate the power to go beyond.

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...
