The production of very neutron-deficient isotopes near Sn-100 has been investigated by using on-line mass separation of evaporation residues produced by heavy-ion induced complete-fusion reactions. We measured the cross sections for Cd-99, In-100, Sn-101 and In-102 via Ni-58 + 58Ni fusion reactions followed by cluster emission, and via Ni-58 + Cr-50 fusion reactions accompanied by evaporation of protons, neutrons or cu particles. Both types of reactions yield similar cross sections for the production of exotic nuclei near Sn-100. The data are discussed in comparison with results obtained from statistical-model calculations.
