Structure Factors of Molten CsCl at Low Q

Abstract The structure factors for three samples of molten CsCl with different isotopic chlorine compositions have been measured accurately in the region 0.2 > Q > 3.0 A−1 using the D1B diffractometer at the Institut Laue Langevin. A rise in the measured structure factors for Q > 0.5 A−1 is explained as being due to inelastic scattering from overdamped acoustic modes.
