dc.description.abstractEnIn an experiment at the SISSI/LISE facility of GANIL, we used the projectile fragmentation of a 78Kr primary beam at 73 MeV/nucleon to produce new isotopes of astrophysical interest. We obtained clear evidence for the existence of the five new isotopes 60Ga, 64As, 69,70Kr, and 74Sr. However, we did not find any evidence for 69Br, whereas comparable nuclei were observed with more than 1000 counts. The isotope 69Br is thus deduced to be a proton-unbound nucleus with a half-life shorter than about 100 ns. The influence of these results on our understanding of the astrophysical RP process is discussed.
