摘要：

Chemically induced dynamic nuclear polarization (H-1 CIDNP) was observed during photolysis of uranyl succinate containing 30% of U-235 in methanol-d4 and D2O. The photolysis of the succinate up to 85%-90% conversion results in an enrichment of the starting compound in the U-235 isotope by 6%+/-1% due to a magnetic isotope effect with the U-235/U-238 pair.
