Partial Structural Functions of Molten CuBr Estimated from the Anomalous X-Ray Scattering Measurements

The individual partial structural functions of molten CuBr have been estimated from the anomalous X-ray scattering (AXS) measurements. This data processing includes the help of the reverse Monte Carlo (RMC) simulation technique. The cation-cation structure factor of a CuCu ( Q ) was found to be rather structureless and the closest Cu–Cu distance in molten CuBr was significantly smaller than that for Br–Br, indicating the like-ion penetration into the first unlike-ion coordination shell, similar to the molten CuCl case. It is then suggested that a disordered close packing of Br - ions where Cu + ions meander so as to take strongly disordered distribution by penetrating through the tetrahedral holes.
