Definition

quantum number related to the total angular momentum (total angular momentum), $J$ , of a nucleus in any specified state, normally called nuclear spin:

J^{2} = {P{hbar}}^{2} I (I + 1)

where $P{hbar}$ is the reduced Planck constant (ISO 80000-1)

nombre quantique associé au moment cinétique total (total angular momentum), $J$ , d'un noyau dans tout état spécifié, généralement appelé spin nucléaire:

J^{2} = {P{hbar}}^{2} I (I + 1)

où $P{hbar}$ est la constante de Planck réduite (ISO 80000-1)

Notes

Nuclear spin is composed of spins of the nucleons (protons and neutrons) and their (orbital) motions.

In principle there is no upper limit for the nuclear spin quantum number. It has possible values $I = 0, 1, 2, \dots$ for even $A$ and $I = \frac{1}{2}, \frac{3}{2}, \dots$ for odd $A$ .

In nuclear and particle physics, $J$ is often used.

Le spin nucléaire est composé des spins des nucléons (protons et neutrons) et de leurs mouvements (orbitaux).

En principe, le nombre quantique de spin nucléaire n'a pas de limite supérieure. Ses valeurs peuvent être $I = 0, 1, 2, \dots$ pour $A$ pair et $I = 1 / 2, 3 / 2, \dots$ pour $A$ impair.

En physique nucléaire et particulaire, $J$ est souvent utilisé.
