Abstract
Double‐cell integrals of the cell‐cluster theory have been evaluated by Monte Carlo numerical integration for hard spheres, and for molecules interacting with a Lennard‐Jones potential at three temperatures. The volumes studied are rather higher than normal liquid volumes, the lowest being V*=2. Under these conditions, cell‐cluster theory based on only single‐ and double‐cell contributions gives poorer agreement with experiment than single‐cell theory. The question of whether these conclusions extend to the region of normal liquid densities is unanswered at present.
