DEF

a fundamental interaction experienced by elementary particles that is responsible for some particle decay processes, for nuclear beta decay, and for emission and absorption of neutrinos.

Domaine(s)
  • Physique atomique
CONT

Aux deux champs fondamentaux responsables [des phénomènes de la gravitation et de l'électromagnétisme] s'en ajoutent en réalité deux autres, apparus avec la physique nucléaire [...]: ce sont le champ des interactions "fortes" (ou nucléaires) [...], et le champ des interactions "faibles", qui se manifeste dans la radioactivité [bêta] des noyaux et dans la plupart des désintégrations des particules élémentaires.
