Studies on fractionation of ytterbium isotopes in Yb(III)-acetate/Yb-amalgam system. Even-odd effect

Creators

Description

The fractionation of ytterbium isotopes with the even and odd numbers of neutrons was investigated in a Yb(III)-acetate/Yb-amalgam exchange systems. The light isotope was preferentially fractionated to the amalgam phase. The values of the unit separation gain per mass difference,ε, were found to be -0.00054 for 176/171Yb and -0.00069 for 176/174Yb The difference which amounted to 0.00015 is an evidence for the occurrence of the so called 'even-odd' effect. It was also found that the chemical isotope shift of ytterbium was monitored by optical isotope shift its atomic spectra. (author)
