Abstract

An apparatus for controlling the glancing angle of incident beam from a synchrotron source has been newly built for structural studies of high temperature liquids by the anomalous X-ray scattering (AXS) method in the reflection mode. The usefulness and capability of this apparatus were demonstrated by obtaining the individual partial structural functions of the liquid Bi30Ga70 alloy using the energies close to the Ga K and Bi LIII absorption edges. The data processing for estimating three partials includes the intensity data obtained at the energy of 15.0 keV, which is far from both edges and the reverse Monte Carlo (RMC) simulation technique. The resultant partial structural function for Ga-Ga pairs was found to be rather similar to that of pure Ga. On the other hand, partial structural function for Bi-Bi pairs differs from the pure Bi case and the coexistence of more than two species is rather well-recognized in the Bi30Ga70 liquid alloy.
