Radial Distribution Functions in Binary Gas Mixtures

The equations of Born and Green are generalized to the two component case. An approximate solution is formally obtained by a linearization procedure and is found to contain a singularity which is tentatively identified with the gas‐liquid branch point of the radial distribution function. Temperature‐density relations are found in the critical region by roughly locating this singular point. The results lend weight to the hypothesis that the singularity corresponds to the branch point.
