Description

The extraction behaviour of rutherfordium (element 104, Rf), carrier-free zirconium, and hafnium in the system HCl-TBP (tributylphosphate) was examined. The 65-s α-emitting isotope 261Rf was produced via the reaction 248Cm(18O,5n). The recoil products were transported with a He(KCl) jet to the automated rapid chemistry apparatus (ARCA) where 1140 separations were performed. In contrast to previous data showing a seemingly low extraction of Hf and Rf we find much higher distribution coefficients. The extraction increases in the order Hf<Rf<Zr. (orig.)
