Abstract:

The work of the program developed around two themes 1 Ionic Mobility in the Alkali Halides, and 2 Color Centers in the Alkali Halides. The most significant results obtained on ionic mobility were the evidence for a contribution of vacancy pairs to the self-diffusion coefficient of the chloride ion in sodium chloride and the evidence for a high-temperature, high-frequency dielectric loss due to vacancy pairs in the alkali halides. Although much detailed information was obtained concerning the interaction and relationships of H, V, F, and a color centers in the alkali halides, the most important contributions were 1 the evidence that the H optical absorption band formed by x-rays at low temperatures is composed of overlapping bands due to H and V sub K centers and the determination of the position and shape of the band due to H centers, and 2 the evidence that interstitial particles H centers or interstitial halogen atoms can be formed by low energy, ultraviolet photons in crystals containing the hydroxyl ion as an impurity.
