Monte Carlo Simulation for Spheres with Two Length Scales
  Canonical ensemble Monte Carlo calculations have been carried out on spheres with two different length scales. Radial distribution functions at various temperatures and densities were computed and compared. Preliminary results indicate that there are differences but because these may be subtle, more calculations including self-diffusion coefficient, heat capacity, etc. would be necessary in order to determine a phase diagram.
