Abstract

As part of an effort to develop aqueous isotope harvesting techniques at radioactive beam facilities, ⁴⁸V and a cocktail of primary- and secondary-beam ions created by the fragmentation reaction of a 160 MeV/nucleon ⁵⁸Ni beam were stopped in an aqueous target cell. After collection, ⁴⁸V 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 ⁴⁸V 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.
