In an experiment at the SISSI/LISE facility of GANIL, we produced proton-rich isotopes in the selenium-to-strontium region by projectile fragmentation of a 78Kr primary beam at 73 MeV/nucleon. The emission of P-delayed protons from h7Se, 7'Kr, and 75Sr was observed for the first time and the corresponding branching ratios were determined. The proton energy spectra were compared to predictions of a statistical model. The half-lives of 67 Se, 7' Kr, and 75Sr were deduced from the time characteristics of the observed proton activity. The half-life of 75Sr was measured for the first time. For “Se and 7'Kr, the obtained half-lives are compared to previous measurements.< Réduire
