“…4) yields activation energy of 0.13 eV ± 0.02 in the temperature range from 530 to 810 K. This value is close to activation energies for H center migration in LiF obtained by other authors [8,9]. In the case of F centers and their aggregates, the activation energy is known to be considerably higher (0.6-1.7 eV) [10,11]. The obtained result points to a possible role of interstitial halogen defects in the recovery processes.…”

“…The essence and application of the absorption optical method for quantitative and qualitative analysis of defects of radiation origin in solids are described in [1][2][3][4][5][6][7][8]. Articles [1][2][3][4][5][6][7][8] demonstrate the results of using the method for the study of radiation defects in ionic crystals.…”

“…It is known today [1][2][3][4][5][6][7][8] that ionic crystals have found wide application in optics (crystal monochromators in Xray spectral optics, lenses, transparent optical media (light filters) of optical instruments), in detector and laser technology. It is known that when ionizing radiation passes through ionic crystals, color centers appear in them, which can change the spectral composition of radiation both in the UV region and in the visible range.…”

“…The slope of the linear fit gives activation energies of 1.8 ± 0.2 eV and 0.5 ± 0.02 eV for F 2 and F þ 3 , respectively. It has been shown that activation energy of about 1 eV is necessary to induce F center diffusion [21,22] and 0.5 eV to mobilize the hole centers [22,23]. Bouchaala et al have calculated a value of 1.5 eV for F-type centers activation energy [24].…”
