The relaxations due to vacancies in copper have been calculated using lattice statics method. Using the measured phonon dispersion relation of copper by Sinha and the elastic constants as constraints, the dynamical matrix is derived including interactions up to five neighbours. Unlike most of the previous calculations all the neighbours are found to relax towards the vacancy. Distortions are found to be large in close‐packed directions as compared to the directions along the cube axes in the crystal.
