Temperature dependence of the dynamic interstitial interactions in potassium bromide

Formation of the H and H_A centers in Na⁺-doped KBr within the time constant of the thermal annihilation of the H center is measured between 80 and 200K and it is shown that the volume of the interaction of the radiation-induced replacement sequence of an interstitial halogen with a Na⁺ impurity increases with an activation energy of (0.025 ± 0.005) eV as the temperature rises.
