Question

Vector-like objects representing this quantity only return to their original state after a 720 degree rotation. For 10 points each:

[10e] Name this intrinsic angular momentum of a quantum particle. Electrons in the same orbital must have this quantity’s opposite values of “up” and “down.”

ANSWER: spin [accept spinors]

[10h] The spin states of a two-particle system can be calculated using these doubly-eponymous coefficients, which undergraduates typically reference in an arcane set of diagonally-oriented tables.

ANSWER: Clebsch–Gordan coefficients [prompt on CG coefficients]

[10m] The spin operators in each Cartesian direction equal the Pauli matrices times this constant over two. Part of the symbol for this constant indicates that it equals another constant divided by two pi; you may name the constant or the symbol.

ANSWER: reduced Planck’s constant [or h-bar; reject “Planck’s constant” or “h”]
