摘要：
Cohesive energies, lattice constants, and bulk moduli have been calculated for the rare-gas crystals Ne through Xe. The results are based on a many-body expansion of the interaction energy, with two- and three- atom contributions evaluated in valence-only coupled-cluster calculations using relativistic pseudopotentials. Although the two-body contributions dominate the cohesive energy in all cases, the influence of three-body contributions is non-negligible and reaches nearly 7% of the cohesive energy for Xe.
