Dubnium-262 was produced in the Cm(F, 5n) reaction at the JAEA tandem accelerator. Reaction products were rapidly transported by a He/KF gas-jet system to the chemistry laboratory. Anion-exchange behavior of Db in HF/HNO solution was then investigated using the newly developed on-line ion-exchange and -particle detection apparatus. Distribution coefficients of Db were clearly smaller than those of Ta, the closest homologue in the periodic table, and were close to those of lighter homologue Nb and also the pseudo homologue Pa. Fluoride complex formation of Db will be discussed.

Cation-exchange behavior of Rf (T = 78 s) produced in the Cm(O, 5n) reaction was studied on a "one-atom-at-a-time" scale in HSO (0.15-0.69 M)/HNO mixed solutions ([H] = 1.0 M) using an automated ion-exchange separation apparatus coupled with the detection system for alpha-spectroscopy. It was found that adsorption probability (%ads) of Rf on cation-exchange resin decreases with increasing [HSO], showing a successive formation of its sulfate complexes. Rf exhibited much weaker formation of the complexes than the lighter homologues Zr and Hf, which is qualitatively in good agreement with theoretical calculations including relativistic effects.
