Abstract
The presence of the separation effect was established for terbium-154 atoms, which contain isomer nuclei and nuclei in the ground state, during the chemical isotopic-exchange reaction in an organic solution of the TbCl3-Tb amalgam chemical system. Experiments on the separation of a natural mixture of ytterbium isotopes were performed in an analogous chemical system. The coefficients of separation of ytterbium isotopes were calculated on the basis of the isotopic-analysis data. The relative contributions of the effects of differences in masses, charge radii, and nuclear spins of isotopes to the coefficients of separation of ytterbium isotopes were estimated in the Bigeleisen approximation (1996). The conclusion on the possibility of separating nuclear isomers using the method of chemical isotopic-exchange reactions owing to differences in the nuclear shapes, sizes, and spins in the isomeric state was drawn.
