Abstract The effect of plastic deformation and heat treatment on the room temperature production of F centers, M centers, and V centers by Co/sup 60/ gamma rays was investigated. Deformation of an irradiated sample caused a reappearance of the first Stage'' coloration for F centers when the sample was irradiated further. This deformation induced enhancement of the colorability could be annealed out by heat treating the samples in air at 450 deg C for 20 min. It was also observed that the coloration curves for the V/sub 2/ band were very similar to those for the F band, and that they were affected by deformation, heat treatment, and optical bleaching in the same way.
