An attempt to observe inelastic neutron scattering from short; wavelength charge fluctuation modes in molten potassium bromide is described. Measurements were made using a triple axis crystal spectrometer with fixed scattered neutron energy (19 THz, or 78.6 meV) and scans were recorded at scattering angles between 2 degrees and 7 degrees . An analysis of the results indicates weak shoulders on each side of the elastic peak, corresponding to energy transfers about 4 THz. A calculation of the expected scattering, based on the computer simulation results of Hansen and McDonald (1975) is described, and the neutron scattering results are discussed in the light of this calculation.
