• Discussion of single-particle and two-particle quantum numbers, uncoupled and coupled schemes
• Discussion of angular momentum recouplings and the Wigner-Eckart theorem
• Applications to specific operators like the nuclear two-body tensor force

For quantum numbers, chapter 1 on angular momentum and chapter 5 of Suhonen and chapters 5, 12 and 13 of Alex Brown. For a discussion of isospin, see for example Alex Brown's lecture notes chapter 12, 13 and 19.
