Magnetic Isotope Effect in the Uranium Isotopes Separation

When uranyl nitrate is photolysed in the water solution, light isotope \({}^{235}{\rm U}\) is separated from isotope \({}^{238}{\rm U}\) ; an enrichment factor \(K = 1.04\) . The initial samples were depleted by a light isotope of uranium \({}^{235}{\rm U}\) (degree \(\beta = 0.00455\)). Regenerated uranyl nitrate was enriched by an isotope of uranium \({}^{235}{\rm U}\) (degree \(\alpha = 0.00464\)). Uranium tetrafluoride was depleted by an isotope of uranium \({}^{235}{\rm U}\) (degree \(\beta = 0.00446\)). Uranium isotopes are separated by the magnetic isotope effect (MIE) in uranyl nitrate photoreduction.
