hello! j'espere qu'il n'est pas trop tard pour les questions!

Selon moi, le gallium, se transforme en Zinc selon une béta+, dont l'énergie maximale des électrons serait de 2,92Mev - le seuil de 1,022, cependant l'item B est compté faux, je ne comprends pas mon erreur..

si quelqu'un pouvait m'éclairer..merci d'avance 🙂
