Abstract
A chemical process for isotopic enrichment of uranium involving the steps of exciting a chelated uranium compound (e.g. hydrated uranyl acetate complex in aqueous solution) to an excited electronic state wherein the excited state preferentially reacts at different rates by virtue of dissimilar nuclear magnetic moment contributions to the chemical kinetics of alternative excited state reaction pathways (e.g. return to ground state by intersystem crossing by electron-nucleus hyperfine coupling vs free radical formation and subsequent precipitation of the hydrated basic salt of uranyl acetate).
