Description
237U was obtained in the 238U (γ, n) 237U reaction in the electron accelerator - microtron МТ-25 of the Flerov Laboratory of Nuclear Reactions (FLNR JINR, Dubna). The method of recoil atoms capture with application to the nanostructure material – hydrous manganese dioxide (cryptomelane-type) in a solid-solid system was used for the separation of 237U and 238U . The change of the distribution coefficient of the isotope 237U between solution and sorbent in dependence on the acidity of nitrate solutions was studied. These experiments show that most of the 237uranium is in the +4 valence state.
