Several new isotopes, In-96, Cd-94, Ag-92, and Pd-90, have been identified at the RIKEN Nishina Center. The study of proton drip-line nuclei in the vicinity of Sn-100 led to the discovery of new proton emitters Ag-93 and Rh-89 with half-lives in the submicrosecond range. The systematics of the half-lives of odd-Z nuclei with T-z = -1/2 toward Sn-99 shows a stabilizing effect of the Z = 50 shell closure. Production cross sections for nuclei in the vicinity of Sn-100 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.
