"A theoretical expression for a cell-center distribution function was developed using a fundamental statistical mechanics approach. A free volume picture of the liquid was used with each atom located in a spherical cell formed by its nearest neighbors. Cell-center density distribution curves were obtained for liquid argon for temperatures of 84.4°K, 91.8°K, 126.7°K, 144.1°K, and 149.3°K and for argon gas at 149.3°K, and a comparison made with the experimental atomic distribution curves obtained by Eisenstein. For the first two temperatures a sharper, more definite structure was predicted by the cell model. For the remaining four temperatures, with the assumptions made, a periodic structure of regularly decreasing atomic concentrations was predicted. Cell-center distribution curves 4πr2ρc(r) were obtained for temperatures of 84.4°K and 91.8°K and the positions and co-ordination numbers of the first and second atomic concentrations were found. A reasonable agreement was found between the values obtained by Eisenstein and those obtained here"--Summary, page 35.
