11. Examples are the total angular momentum operators. 12. At that rate, the total angular momentum would be ~ 10 82 J-s. 13. In quantum mechanics, the scalar value \ ell is referred to as the total angular momentum . 14. The quantum number " J " refers to the total angular momentum , as before. 15. The contributions of the individual electrons and nucleus to the total angular momentum do not cancel each other. 16. Examples being the electron-electron repulsion, magnetic dipolar coupling, and total angular momentum -squared operators. 17. This phenomenon of having multiple particles in the same total angular momentum configuration is called " degeneracy ". 18. If this is taken into account, you should find out that total angular momentum of the system is conserved. 19. In simpler terms, the total angular momentum operator characterizes how a quantum system is changed when it is rotated. 20. The total angular momentum conserved in interaction processes is then the sum of the orbital angular momentum and the spin.
