The total value of this property for an atom can be obtained by using Russell-Sanders coupling to combine contributions from orbital and spin components. A deficiency in this quantity during beta decay led Wolfgang Pauli to hypothesize the neutrino.

A deficiency in this quantity during beta decay led Wolfgang Pauli to hypothesize the neutrino. Its conservation by (*) Noether's theorem is the basis of Kepler's second law of planetary motion, and torque is the time derivative of this quantity according to Newton's second law. For 10 points, name this vector quantity, defined as the product of the moment of inertia and the angular velocity.
