Exact Pair Correlations in a One-Dimensional Fluid of Hard Cores with Orientational and Translational Degrees of Freedom

摘要

Exact direct and usual pair correlations for a fluid of anisotropic hard cores with orientational as well as one-dimensional translational degrees of freedom are obtained. These results indicate that previous approximations for the direct correlations in anisotropic hard-core fluids have overlooked the effect of orientational configurations for which the hard-core overlap is not a smooth function of particle separation beyond the point of hard-core contact.
