S. Lahiri et al., Separation of carrier-free ytterbium and thulium produced in 80 MeV C-12(6+) irradiated gadolinium foil target by liquid-liquid extraction with HDEHP, APPL RAD IS, 52(4), 2000, pp. 797-802
Heavy ion activation of natural gadolinium foil with 80 MeV C-12(6+) result
s in the formation of carrier-free ytterbium isotopes, (165.166.167)yb and
their corresponding decay products, Tm-165,Tm-166.167, in the matrix. Carri
er-free ytterbium and thulium isotopes have been separated quantitatively f
rom the bulk target matrix gadolinium by employing di-(2-ethylhexyl)phospho
ric acid (HDEHP) as a liquid cation exchanger. (C) 2000 Elsevier Science Lt
