Neutron diffraction data have been taken for two states on the 218 °K isotherm of krypton. The isothermal pressure derivative of the fluid structure factor is interpreted in terms of the triplet correlation function using an expansion due to Abe. It is concluded that three terms in Abe's expansion explain the data to a first approximation, but significant discrepancies remain.

Triplet Correlation Function

Computer simulation data on structural properties [spherical harmonic expansion coefficients of the full pair correlation function g(1,2), radial slices through g(1,2), the background correlation function y(1,2), and the triplet correlation function (for hard spheres), various angle averages of g(1,2) and, for hard spheres, also the direct correlation and bridge functions] of pure hard body fluids known to date have been critically assessed and tables of selected data are presented. In addition to the tables, parametrizations of the data are also given whenever they have been available. The molecular models considered include both convex body models (spheres and prolate spherocylinders) and interaction -site models (homo- and heteronuclear diatomics, linear and nonlinear symmetric triatomics, and tetrahedral penta-atomics).
