Analytical representation of the percus-yevick hard-sphere radial distribution functionf

Explicit analytical expressions, written in terms of complex variables and suitable for rapid computer evaluation, are presented for the Percus-Yevick hard-sphere radial distribution function, g(R), for R≤σa. Some effects of truncating g(R) to unity past R =5 σ are discussed. © 1970 Molecular Physics.
