The closed form structure factor for a hard sphere system arising from the known solution of the Percus-Yevick equation is matched with the experimental data for liquid He, Ne, Ar, Kr and Xe and the hard core diameters deduced are found to be in good agreement with the values appropriate to the law of corresponding states applied to the gaseous phase. Small deviations in the case of liquid He are attributable to quantum effects.
