Elastic displacement field of point defects in anisotropic cubic crystals

  • Published:
Zeitschrift für Physik A Hadrons and nuclei

Abstract

The elastic displacement field of point defects in cubic crystals is calculated for weak anisotropy by second order perturbation theory and by a variational procedure. The results are compared with numerical calculations for Cu. Further analytical approximations are given for the volume change in an infinite crystal and for the interaction energy of two point defects.
