The isotope effect includes a mass-dependent effect caused by intramolecular vibrational energy and a mass-independent effect caused by the nuclear volume effect. The mass-independent effect is called the ”Odd-Even mutation” because odd-mass isotopes behave differently than even-mass isotopes. A phenomenon similar to this effect was also discovered in heavy elements in meteorites, and it is considered important to elucidate the mechanism of the nuclear volume effect in the field of cosmochemistry (Fujii et al., 2006). Solvent extraction experiments show similarities in isotope even / odd differences and mass ratio-dependent isotope fractionation (MIF) results (Moynier et al., 2008) to understand the mechanism of MIF variation. Solvent extraction experiments are considered useful. In this experiment, we focused on Sn, which shows a large MIF in solvent extraction, and aimed to clarify the relationship between MIF and the nuclear volume effect by performing isotope analysis of Sn during solvent extraction.
