Abstract

As part of an effort to develop aqueous isotope harvesting techniques at radioactive beam facilities, V and a cocktail of primary- and secondary-beam ions created by the fragmentation reaction of a 160 MeV/nucleon Ni beam were stopped in an aqueous target cell. After collection, V was separated from the mixture of beam ions using cation-exchange chromatography. The extraction efficiency from the aqueous solution was (47.0 ± 2.5)%, and the isolated V had a radiochemical purity of 95.8%. This proof-of-concept work shows that aqueous isotope harvesting could provide significant quantities of rare isotopes which are currently unavailable at conventional facilities.

摘要

作为在放射性束流设施中开发水相同位素收集技术工作的一部分，钒以及由160 MeV/核子的镍束流碎裂反应产生的初级和次级束流离子混合物被注入到一个水相靶室中。收集后，使用阳离子交换色谱法将钒从束流离子混合物中分离出来。从水溶液中的萃取效率为(47.0 ± 2.5)%，分离出的钒的放射化学纯度为95.8%。这项概念验证工作表明，水相同位素收集可以提供大量目前在传统设施中无法获得的稀有同位素。
