Abstract
Abstract This paper reports the yield of no-carrier-added (NCA) radionuclides produced in 12C6+ induced reaction on natural yttrium target at 10 different incident energies in the range of 40 to 75 MeV by the stacked-foil technique, followed by off-line γ-ray spectroscopy. It also reports the radiochemical separation of NCA 97Ru from the bulk yttrium target. 97Ru was produced in the yttrium matrix through 89Y(12C, 4n)97,97mRh(EC)97Ru and 89Y(12C, p3n)97Ru reactions along with the radioisotopes 98Rh, 97Rh, 97mRh, 93Tc, 94Tc, 95Tc and 93mMo. Irradiated target was allowed to cool for the complete decay of short-lived residues and 97Ru was then separated from the bulk yttrium using the cation exchanger DOWEX-50WX4 in an ion exchange column as well as via solid-liquid extraction (SLX). A total of ∼88% NCA 97Ru was separated in column chromatography without any contamination of bulk, whereas quantitative separation of NCA Ru was achieved in SLX.
