Salut,

alors il s’agit bien de la B+ qu’il y a une emission de paires de photons de 511KeV. (Tu peux t’en souvenir en te disant que si pour les calculs d’énergie pour les transformations B+ tu dois toujours enlever 1,022MeV c’est justement par rapport à cette emission de paire de photons. (511*2 = 1022 keV = 1,022 MeV).
