Publisher's Synopsis
This reference treats the development of angular momentum theory in a consistent way, beginning with the geometrical concept of rotational invariance. New concepts are introduced and relevant formulas derived in the natural context of the treatment. For the student and researcher, end-of-chapter exercises present examples of the applications of angular momentum theory to subjects of current interest.;Included for practical reference are tables of formulas, and brief computer programs for reduced rotation matrix elements and for 3-j, 6-j and 9-j coefficients.
