After selection by means of the LISE3 separator, the isotopes of interest were implanted in a silicon 26detector telescope where their half-lives (T = 46.3(22) ms for P and T = 15.5(15) ms for 1/2 1/227S) and their main decay branches were measured. A decay scheme is proposed for both isotopes, including β-delayed p & 2p and γ-ray spectroscopy. 1) Introduction La radioactivité deux protons, c'est-à-dire l'émission d'une paire de protons à partir d'un état nucléaire, bénéficie, du point de vue énergétique, de l'énergie d'appariement.
