Principe de l'émission Auger. L'électron incident en vert, émis par le canon, vient percuter un électron de la couche 1s. L'éjection de cet électron entraîne une perte d'énergie compensée par une transition d'un électron de la couche 2s vers la couche 1s. On a alors une émission d'un rayonnement qui entraîne le départ de l'électron Auger. 2, record 8, French, - %C3%A9mission%20Auger
