Structure of beta-Uranium
The beta-structure of uranium metal is stable between 935 and 1045 K. Profile refinements of time-of-flight neutron diffraction data show that the space group of this structure is P4(2)/mnm. This finding ends a long controversy dating back to the 1950s. The details of these experiments and analyses, which include the separation of the crystalline scattering of the powdered uranium from the diffuse scattering of a fused silica container and a comparison of results from powder and polycrystalline rod samples, are reported.
