NEUTRON SCATTERING ON LIQUID ARGON AT SEVERAL DENSITIES AND TRIPLET CORRELATION FUNCTIONSP. Verkerk
Interuniversitair Reactor Instituut, 2629 JB Delft, The Netherlands
Recently two sets of thermal neutron scattering time-of-flight measurements on liquid argon at 120 K were published. The combined results provide the static and the dynamic structure factor at five densities. The first and second isothermal density derivatives of the static structure factor have been evaluated. The derivatives have been compared with the uniform fluid model and with a simple model for g3 based on the h-bond expansion by Abe. In both cases the agreement is unsatisfactory. The first density derivative of the dynamic structure factor has been evaluated and agrees qualitatively with calculations by Groome, Gubbins and Dufty.
