Activation energies for the migration of K + and N 0 interstitials in KN 3 crystals are calculated. The total cohesive energy is obtained from a modified Born model. Both double‐spherical and triple‐spherical potentials are used as the repulsive interaction. Polarization effects according to the Hatcher‐Dienes scheme are employed. N 0 interstitial migration is found to require very little energy and thus becomes a good candidate for explaining the explosive instability of the azides.
