The role of zero‐point motion and three‐body interactions (TBI) is investigated in describing the numerous crystal properties of rare gas solids (RGS). The model used is made less parametric in nature by incorporating the effect of TBI via overlap integrals evaluated by Hafemeister. Remarkably good agreement is achieved between theoretical and experimental results on cohesive, harmonic, and anharmonic elastic and thermophysical properties of RGS.
