Lennard-Jones potential - Wikipedia
WebbThe most popular potential to model excluded volume interactions is the Lennard–Jones (LJ) potential: originally derived for argon atoms. It has short-range repulsion for r < 2 1/6 σ followed by a weak attraction part. In practice, one has to introduce a cutoff for computational reasons.
