Partial Structural Functions of Molten RbBr Estimated from the Anomalous X-ray Scattering Data

Abstract

The anomalous x-ray scattering (AXS) measurements for molten RbBr have been made using the energies close to the Rb K (15.202 keV) and Br K (13.470 keV) absorption edges for estimating three partial structural functions of Rb-Rb, Br-Br and Rb-Br pairs. The data processing for obtaining three partials includes the intensity data obtained at the energy of 17.0 keV, which is far from both edges and the help of the reverse Monte Carlo (RMC) simulation technique. The resultant partial structural functions of molten RbBr suggest that the configuration in the first Rb-Br coordination shell is found to be octahedral, as it is in the crystal.
