摘要：

In order to study the change of the atomic arrangement in liquid (l-) alkali halides with volume expansion, the energy-dispersive X-ray diffraction and the density for l-RbCl were measured at temperatures up to 1600-degrees-C, exceeding the boiling point at normal pressure. The structure factor and the pair distribution function were obtained as functions of density. It was found that the average coordination number, N1, decreases substantially with decreasing density, while the nearest-neighbor distance, r1, remains almost constant or decreases very slightly with density decrease.
