Abstract :
The parallel effect of step-wise annealing on induced absorption and thermoluminescence in crystalline LiF and CaF2 irradiated with gamma rays and He+ ions is investigated. The thermoluminescence centers are found to correlate to the entire absorption spectrum rather than to isolated bands. The results also indicate a preferential production of centers of higher thermal stability by the energetic ions, and the possible existence of reservoirs of trapped species resistant to common annealing practices.
