Two of Hund's rules consider the total and orbital values of this for an atom and the Stern- Gerlach experiment established the quantization of an intrinsic form of this, spin.
Yrast refers to a state with minimum energy for a set value of this quantity. In quantum mechanics, this quantity may be found for a system by a coupling process that invokes Clebsch-Gordon coefficients. Two of Hund's rules consider the total and orbital values of this for an atom and the Stern- Gerlach experiment established the quantization of an intrinsic form of this, spin. Noether's theorem relates a space's rotational symmetry to its conservation, which leads to Kepler's second law, and it holds when there is no net external torque. For 10 points, identify this vector quantity equal to the position crossed with the linear momentum.
