Local MP2 periodic study of rare-gas crystals

The Crystal and Cryscor codes (which solve the HF + MP2 equations for periodic systems) have been applied to fcc rare-gas crystals Ne through Xe, the figure reports the cohesive energy versus lattice parameter, both scaled with respect to the experimental value, obtained with the best basis set. Open and filled symbols refer to two techniques for correcting MP2 energies for BSSE.
