Description
We have developed an online rapid chemical operation system for heavy actinide elements. On this study, multi-track microchips were adopted for the rapid extraction experiment. We performed the online experiment using AVF cyclotron at RIKEN. A 238U target was irradiated with a 112.4 MeV/Nucl. 22Ne beam, and 255No nuclei were produced by the 238U(22Ne,5n)255No reaction. The products recoiling out of the target were transported to the laboratory for chemical experiments, dissolved in aqueous solution, and then fed into the multi-track microchips. The 255No isotope was rapidly extracted in the multi-track microchip by means of 0.01 M HDEHP (Di(2-ethylhexyl)phosphoric acid)-toluene solution as the extractant. And α particles emitted from the isotope detected 40 counts in total. The distribution ratio of the rapid extraction of 255No using multi-track microchip showed the dependence of the ionic radius in the order Ca2+<No2+<Sr2+. (author)
