Charged particle activation of natural CeO2 with ≈80 MeV16O7+ results in the formation of carrier free isotopes,151, 152, 153Dy and their daughter products,151, 152, 153Tb, in the matrix. The liquid cation exchanger HDEHP, has effectively been utilised as an extractant in the quantitative separation of the activation products namely151, 152, 153Dy,151, 152, 153Tb from the bulk target matrix of ceric oxide.
