Beschreibungen/Notizen

• It has been shown that besides the overall assessment of the new isotope effect of “size and shape” of nuclei, discovered by Prof. J. Bigeleisen, a specific effect of the nuclear quadrupole can be distinguished from the effect of “size” and analyzed separately. This effect is significant only for those nuclei that have a non-zero quadrupole effect. It has been shown by means of analysis of the experimental data on separation of uranium isotopes in industrial processes ASAHI and CHEMEX that the relative value of the contribution of the quadrupole effect to ln( s/ s′) can be as large as 20% of the overall (“size”+“shape”) effect.
