Abstract
Preliminary data on the fractionation of ytterbium isotopes in a Yb(II I)-acetate/Yb-amalgam exchange system were obtained. The light isotope was preferentially fractionated to the amalgam phase. The values of t he unit separation gain per mass difference, epsilon, were found to be - 0.00054 for Yb-176/171 and -0.00069 for Yb-176/174. The difference, which amounted to 0.00015, may be taken as evidence for the occurrenc e of the so-called ''even-odd'' effect. It was also found that the che mical isotope shift of ytterbium was mirrored by the optical isotope s hift in its atomic spectra.
