“…Correcting for multiple scattering is generally a complex, iterative procedure where the multiple scattering smearing profile is estimated and removed from the data [114]. It becomes even more complicated for samples with direction-dependent sample thicknesses and hence different multiple scattering probabilities [12,174]. One avenue for simplifying the correction and estimation is by approximation of the multiple scattering effect as mainly consisting of double scattering [24,60,11].…”

“…To extract the structure factor, S(q), standard procedures were applied for the measured intensity, including corrections for the self-absorption [13], the multiple scattering [14], the inelasticity [15] and the incoherent scattering [16]. The normalization was completed by using the data of a vanadium rod measured in the similar manner as the sample.…”

The structures of liquid Hg-Rb alloys were studied as a function of composition with neutron diffraction. In the intermediate Rb concentration range, the obtained structure factors show a small prepeak, which may be evidence of the formation of Hg polyanion units in liquids. The reverse Monte Carlo (RMC) analysis was applied to separate the total radial distribution function into corresponding partial radial distribution functions. Up to 10 at.% Rb, no obvious changes are found for the first peak position of the partial radial distribution functions of the Hg-Hg pair and that of the Hg-Rb pair. Above 20 at. % Rb, the increase of the first peak position between the Hg-Rb pairs appears. At 60 at. % Rb, the nearest neighbor distance between Hg and Hg shows the closest value in the concentration range studied. These results indicate that with the proceeding of charge transfer the solvation structure in the dilute Rb concentration range changes into the structure containing the polyanion formation, composed of Hg species.

“…For each sample, empty container and sample environment contributions were subtracted from the raw data, taking into account absorption effects [28] as well as the incoherent-scattering contribution. A standard multiple-scattering [29] and Placzeck [30] corrections were applied. The PDF analysis was performed by fitting the experimental G(r) using the software PDFGui [31].…”
