The cation-exchange behavior of 261Rf (T 1/2 = 78 s) produced in the 248Cm( 18O, 5n) reaction was studied on a "one-atom-at-a-time" scale in 0.15-0.69M H 2SO 4/HNO 3 mixed solutions ([H +] = 1.0M) using an automated ion-exchange separation apparatus coupled with the detection system for alpha-spectroscopy (AIDA). It was found that adsorption probabilities (%ads) of 261Rf on cationexchange resin decrease with an increase of [HSO 4 -], showing a successive formation of Rf sulfate complexes. Rf exhibits a weaker complex formation tendency compared to the lighter homologues Zr and Hf. This is in good agreement with theoretical predictions including relativistic effects.
