Abstract : Several new isotopes, 96In, 94Cd, 92Ag, and 90Pd, have been identified at the RIKEN Nishina Center. The study of proton drip-line nuclei in the vicinity of 100Sn led to the discovery of new proton emitters 93Ag and 89Rh with half-lives in the submicrosecond range. The systematics of the half-lives of odd-Z nuclei with Tz=−1/2 toward 99Sn shows a stabilizing effect of the Z=50 shell closure. Production cross sections for nuclei in the vicinity of 100Sn measured at different energies and target thicknesses were compared to the cross sections calculated by epax taking into account contributions of secondary reactions in the primary target.
