Thermal Activation Energies in NaCl and KCl Crystals

Abstract

Thermal activation energies were computed from various glow peaks of NaCl and KCl single crystals. The method developed in the preceding paper has been used successfully in these calculations. Good agreement was obtained with the results calculated from the initial rise of the glow peaks. Activation energies varied from 0.3 to 1.5 ev for various peaks in the glow curve of NaCl between 150 and 500°K. Similar results were obtained for KCl crystals. The kinetics of the processes was found to be nearly of first order.
