  • denotes the total orbital angular momentum , with single-particle angular momentum. The eigenvalues of are such that and are simply denoted by the letter L. The eigenvalues of are such that and are simply denoted by the letter
  • denotes the total spin , with single-particle spin.The eigenvalues of are such that and are simply denoted by the letter S. The eigenvalues of are such that and are simply denoted by the letter
  • denotes the total angular momentum , .The eigenvalues of are such that and are simply denoted by the letter J. The eigenvalues of are such that and are simply denoted by the letter
  • Keep in mind the addition rules for angular momenta: let us call two arbitrary angular momenta.
