The results from calculations of the mean square displacements of the neighbouring ions of both anion and cation vacancies in sodium chloride are reported. The lattice Green function and scattering matrix technique were applied for three temperatures, 100, 200 and 300K, and for three changes in the force constant parameters due to relaxation of the nearest neighbours towards the vacancy site. The results are compared with the values for the anion and cation of a perfect crystal.
