Abstract
Gamma-ray and 1.5-MeV electron irradiations are employed in the temperature range 25-175 degrees C to produce radiation effects in undoped paratelluri te (alpha-TeO2) single crystals. Optical absorption and ESR techniques are used to study the growth and annealing of point defects, and spectroscopic observations by these two methods are compared. Pulse-annealing experiments are reported over the range 100-500 degrees C. The TeO2 crystal shows much more susceptibility to radiation damage at the higher irradiation temperat ures.
