Title:
TRIPLET CORRELATIONS IN FLUIDS
Author(s):
D.Henderson
Six schemes for calculating the triplet correlation function of a fluid are considered. Four are based upon density expansions and their resummation. The other two approximations are based upon considering one or more of the particles to be the source of an inhomogeneily in the fluid and then using the formalism of the theory of inhomogeneous fluids. In contrast to the other approximations, the two approximations based on the theory of inhomogeneous fluids are inherently asymmetric, although they can be symmetrized easily. A few thoughts about the relative merits of the six schemes are given.
