Identification of new isotopes with the He-jet fed on-line isotope separator KUR-ISOL

The He-jet fed isotope separator on-line (ISOL) facility, KUR-ISOL, has been constructed for the studies on nuclei far from stability produced by fission. The separator can give high-intensity beams of rare-earth elements using a high-temperature thermal ion source. Four neutron-rich isotopes in the rare-earth region, 152Ce, 154Pr, 155Nd and 156Pm have so far been newly identified at this facility. The methods of identification and the implications of the results are presented together with some technical developments on the KUR-ISOL facility recently performed. (author)
