Abstract
The pair distribution function g® plays a central role in liquid state theory, linking structure and thermodynamics. It is typically measured by constructing a histogram of the distances between all pairs of particles, which is used in simulations and experiments where single particle coordinates can be obtained. Here, we present a novel method based on Henderson’s method [1] for measuring the cavity distribution function, going beyond our recent work on particles with hard interactions [2]. The method measures g® in a highly efficient way; moreover, it allows us to obtain an effective pair potential between colloidal particles in experiment.
