In relativistic quantum mechanics, the additional contribution to this quantity of spin is given by the Pauli-Lubanski pseudovector.
In relativistic quantum mechanics, the additional contribution to this quantity of spin is given by the Pauli-Lubanski pseudovector. "Coupling" eigenstates for this quantity in total from separate eigenstates requires use of the Clebsch-Gordan coefficients. This quantity's conservation gives rise to Kepler's third law of planetary motion. For a rotating body, this quantity is equal to the product of angular velocity and moment of inertia. For 10 points, name this quantity, symbolized L, the rotational analogue of linear momentum.
