Abstract
The production of isotopes near 100Sn has been investigated by using on-line mass separation of evaporation residues produced by heavy-ion induced complete fusion reactions. We measured β-delayed protons and γ-rays, deduced the mass-separated beam intensities for 99Cd, 100In, 101Sn and 102In, and determined the corresponding production cross-sections σ for 58Ni+58Ni reactions followed by emission of nuclear clusters, and for 58Ni+50Cr reactions accompanied by emission of protons, neutrons and α particles. The results indicate that the σ values for reactions followed by emission of clusters are comparable with those for reactions proceeding through light particle emission. Due to recoil-loss effects in on-line mass separation, the former mechanism is less suitable than the latter one for producing such neutron-deficient nuclei in this kind of experiments.
