Abstract

Gamma-ray and 1.5-MeV electron irradiations are employed in the temperature range 25-175°C to produce radiation effects in undoped paratellurite (α-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°C. The TeO2 crystal shows much more susceptibility to radiation damage at the higher irradiation temperatures.
