Notes

$j_{i}$ refers to a specific particle $i$ ; $J$ is used for the whole system.

The quantum number $J$ and the magnitude of total angular momentum $J$ (total angular momentum) are different quantities.

The two values of $j$ are $l \pm 1 / 2$ . (See orbital angular momentum quantum number.)

$j_{i}$ correspond à une particule spécifique $i$ ; $J$ est employé pour le système complet.

Le nombre quantique $J$ et la norme du moment cinétique total $J$ (total angular momentum) sont des grandeurs différentes.

Les deux valeurs de $j$ sont $l \pm 1 / 2$ . (Voir orbital angular momentum quantum number.)
