Mystery of Uranium Oxidation Configuration in Hexagonal U3O8
Abstract: Uranium oxides are important materials in the nuclear fuel cycle. Triuranium octoxide (U3O8) is the most stable of these compounds, and it happens to display a peculiar effect: the uranium atoms are separated into two sites: two U(V) and one U(VI) oxidation state. But at elevated temperature the crystal structure has only one U site. How are 16 electrons distributed across the three identical uranium sites? The mystery may involve the subtle rearrangement of oxygen atoms, the influence of lattice vibrations, and a fast "electron-hopping" mechanism. Using high-resolution neutron diffraction, we hope to track subtle movements of oxygen atoms in U3O8, which we hope will provide some guidance about the interplay of these effects.
