Definition

characteristic quantum number $s$ of a particle, related to its spin (spin), $s$ :

$s^{2} = {P{hbar}}^{2} s (s + 1)$

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

nombre quantique caractéristique $s$ d'une particule associé à son spin (spin), $s$ :

$s^{2} = {P{hbar}}^{2} s (s + 1)$

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

Notes

Spin quantum numbers of fermions are odd multiples of $1 / 2$ , and those of bosons are integers.

Les nombres quantiques de spin des fermions sont des multiples impairs de $1 / 2$ , et ceux des bosons sont des entiers.
