Abstract :
Two absorption bands in transparency region in high-energy electron irradiated GaSe crystals have been experimentally found. The optical transmission spectra of the crystals are studied in order to elucidate the origin and energy positions of related defect states. The measurements of optical transmission spectra temperature dependencies, radiation defect annealing and analysis of the optical spectra within existing theoretical models were performed.
