Definition

quantum number of an atom describing the inclination of the nuclear spin with respect to a quantization axis given by the magnetic field produced by the orbital electrons

nombre quantique d'un atome décrivant l'inclinaison du spin nucléaire par rapport à un axe de quantification donné par le champ magnétique produit par les électrons orbitaux

Notes

The interval of $F$ is $| I - J |, | I - J | + 1, \dots, I - J$ .

This is related to the hyperfine splitting of the atomic energy levels due to the interaction between the electron and nuclear magnetic moments.

L'étendue de $F$ est $| I - J |, | I - J | + 1, \dots, I - J$ .

Cela est associé à la séparation hyperfine des niveaux d'énergie de l'atome du fait de l'interaction entre les moments magnétiques électronique et nucléaire.
