Abstract
The structure of molten CuCl is anomalous when compared with that of the molten alkali halides in the Cu-Cl radial distribution function (RDF) is quite sharp and (ii) no peak in the Cu-Cu RDF is observed. This structural information has been obtained using neutron diffraction (1) and the isotopic substitution technique (2). In a single diffraction experiment, the scattered intensity depends on all the pair distribution functions. For a molten binary salt, there are three such functions which can be determined by three independent diffraction measurements. These are performed on three samples having different isotopic abundances of one or more of the constituent nuclei and thereby different neutron scattering lengths. The resulting diffraction spectra can then be solved for the three individual pair distribution functions.
