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

Electron dose calculations using the Method of Moments
TL;DR: Numerical comparisons with Monte Carlo calculations show that the Method of Moments yields expressions for the depth-dose curve, radial dose profiles, and fluence that are significantly more accurate than those provided by the Fermi-Eyges theory.

Quantum theory of molecule-surface scattering: Rotational transitions
TL;DR: In this article, the quantum theory of atomic scattering from hard surfaces, previously developed to cover molecular scattering, taking into account rotational transitions, was extended to cover atomic scattering, and two methods (a perturbative and a nonperturbative approach) were considered: the former is applied to H 2 scattering, the latter to HD scattering from LiF.

Collision induced light scattering from fluids composed of tetrahedral molecules
TL;DR: In this paper, collision induced isotropic and anisotropic spectra of light scattered from fluids of tetrahedral molecules are examined and the interaction function used includes the dipole-induced dipole effect (DID) and the collision induced rotational Raman effect (CIRR) to lowest order.

The nodal structure of two-electron wave functions on the Wannier ridge
TL;DR: In this article, it was shown that two-electron wave functions with total angular momentum L, spin S and parity π have nodes on the Wannier ridge for all states where S + π is odd.
