A Cell-Center Distribution Function For Liquid Argon, Arthur M. Soellner

Masters Theses

"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, …
