Interatomic Potentials and X-Ray-Diffraction Intensities for Liquid Xenon

Abstract

The experiments performed by Campbell and Hilderband have provided intensity curves for x rays scattered from liquid xenon. They have computed, from their data, the radial‐distribution functions g. The Lennard‐Jones 6–12 potential with constants suggested by Beattie, Barriault, and Brierly and the Slater potential with Kane's constants have been used to compute g's and scattering intensities for comparison with those of Campbell and Hilderband. The agreement between experiment and theory is poorer than that found for neon, argon, and krypton, and arguments are presented why the experimental intensities should be remeasured.
