Angular Momentum in Quantum Mechanics

摘要: This book offers a concise introduction to the angular momentum, one of most fundamental quantities in all quantum mechanics. Beginning with quantization spin and orbital author goes on discuss Clebsch-Gordan coefficients for two-component system. After developing necessary mathematics, specifically spherical tensors tensor operators, then investigates 3-"j," 6-"j," 9-"j" symbols. Throughout, provides practical applications atomic, molecular, nuclear physics. These include partial-wave expansions, emission absorption particles, proton electron quadrupole moment, matrix element calculation practice, properties symmetrical top molecule.
