Abstract
are reviewed. The transactinide nuclide 261 Rf has been successfully produced in the reaction 248 Cm( 18 O, 5n) at the JAERI tandem accelerator. The excitation function of the reaction has been measured with a rotating wheel catcher apparatus and the maximum production cross section has been determined to be about 13 nb. On-line ionexchange experiments on Rf together with the group-4 elements Zr and Hf in acidic solutions have been conducted with a rapid ion-exchange separation apparatus. From the systematic study of the anion-exchange behavior of Rf, it has been found that the properties of Rf in HCl and HNO3 solutions are quite similar to those of Zr and Hf, definitely confirming that Rf is a member of the group-4 elements. However, we have observed an unexpected chemical behavior of Rf in HF solutions; the fluoride complex formation of Rf is significantly different from those of Zr and Hf. The current progress in the Rf aqueous chemistry is briefly summarized and prospects of extending chemical studies of transactinide elements at JAERI are considered.
