Abstract
Potassium chloride and bromide crystals have been irradiated with x-rays at -183°C and the behavior of the , , and optical absorption bands observed during subsequent warming to room temperature. The thermal bleaching of the -band is accompanied by a decrease in the -band, the appearance of free charge within the crystal, and luminescence. The data indicate that positive holes are released from traps during this process.
