Abstract
An alternate calculation to an earlier one (see ibid., vol.8, p.1322, 1975) on the dispersion binding energy of the rare gas solids is presented. the calculation neglects the self-polarisation terms previously included but retains the finite size of the atoms. The calculations give good agreement with other calculations using point-dipoles, but as with the earlier work, the authors are able to compute a more stable FCC structure than HCP. They are able to show that many-body contributions differ for the two structures, and are larger for HCP than for FCC especially for large atomic polarisabilities.Keywords
