Vector coupling of angular

Cle72, Gor75], Their values follow from the general properties of the vector coupling of angular momentum operators. 

Clebsch-Gordon coefficients - A set of coefficients used to describe the vector coupling of angular momenta in atomic and nuclear physics. 

Here, the relevant angular momentum vectors and quantum numbers are L (7), the total orbital angular momentum of the atom, obtained as the vector coupling of those corresponding to the core and to the outer electron(s), S (S), the total spin, and J (7), the total angular momentum for a given atomic level [8] ...

Because of the large number of angular momentum observables involved in the state vectors of systems of more than one electron, it helps greatly in keeping track of the quantum numbers to express the coupling of angular momenta in terms of the symbols of Wigner, which have useful symmetries. 

Christy, R. F. Phys. Rev. 89, 839 (1953)- — This paper discusses the dependence of angular distributions on the type of coupling of angular momentum vectors in the nucleus. Several specific examples are given. 

Given that sin 9w is close to the value 0.25 that makes Ve = 0,Vft = 0, the effect is exceedingly small. However, the angular dependence of the differential cross-section is sensitive to the axial-vector coupling of the 8md gives rise to a forward-backward asymmetry in the angular... 

Their symmetry labels can be obtained by vector coupling (see Appendix G) the spin and orbital angular momenta of the two subsystems. The orbital angular momentum coupling...

I have elected to include a discussion of the variational principle and perturbational methods, although these are often covered in courses in elementary quantum mechanics. The properties of angular momentum coupling are used at the level of knowing the difference between a singlet and a triplet state. 1 do not believe that it is necessary to understand the details of vector coupling to understand the implications. 

Note that, throughout this discussion, we have used lower-case letters when refering to orbitals and upper-case when we mean many-electron wavefunctions. There arises the question of, what are the relationships between I and L, or between s and S . They are determined by the vector coupling rule. This states that the angular momentum for a coupled (i.e. interacting) pair of electrons may take values ranging from their sum to their difference (Eq. 3.11). 

The vector coupling rule applies to all forms of angular momentum ...
