Introduction to the Graphical Theory of Angular Momentum: Case Studies

Robert Luypaert, Jean Van Craen

A theoretical study of quantum-beat intensity profiles is presented for the case of zero-field hyperfine-structure beats. By means of the graphical methods of angular-momentum theory, an explicit expression for the quantum-beat profiles, in the form of a multipole expansion is obtained.

A brief review of the results obtained in Vilnius while developing the graphical methods of quantum angular momentum theory is presented. Numerous modifications and extensions of the original method proposed by A. Jucys, J. Levinson, and V. Vanagas are discussed. The application of the graphical method to the study of one-, two-electron as well as the effective operators and their matrix elements in the coordinate and second quantization representation is surveyed.
