| Jul 15, 2021 at 23:50 | comment | added | ZeroTheHero | Actually angular momentum does not act (algebraically) in $L^2(\mathbb{R}^3)$, but in a direct sum of Hilbert spaces of different dimensions. The Hilbert space of dimension $2j+1$ occurs exactly $2j+1$ times in the full Hilbert space by Peter-Weyl theorem. Basis functions can be chosen to be in terms of real coordinates, but the choice of basis functions is inessential to the formalism of QM. | |

The assignement in the table is consistent with angular momentum conservation at the quantum level en.wikipedia.org/wiki/Elementary_particle | |
