Abstract
Charged particle activation of natural CeO2 with similar to 80 MeV O-16(7+) results in the formation of carrier free isotopes, Dy-151,Dy-152,Dy-153 an d their daughter products, Tb-151,Tb-152,Tb-153, in the matrix. The liquid cation exchanger. HDEHP, has effectively been utilised as an extractant in the quantitative separation of the activation products namely Dy-151,Dy-152 ,Dy-153, Tb-151,Tb-152,Tb-153 from the bulk target matrix of ceric oxide.
