ANGULAR MOMENTUM IN QUANTUM MECHANICS

This book offers a concise introduction to the angular momentum, one of the most fundamental quantities of quantum mechanics.Beginning with the quantization of angular momentum (spin and orbit), the author goes on to discuss the Clebsch-Gordan coefficients for a two-component system.The theory of spherical tensors and tensor operators is developed, and then the vector-coupling coefficients (3-j, 6-j and 9-j coefficients) and their properties are investigated.The author provides practical applications to atomic, molecular and nuclear physics.This book, published first in 1957 (see the review in Zbl 0079.42204), has always been and remains to be a standard source reference for those working in quantum theory of…
