چکیده انگلیسی
Color center creation in LiF crystals irradiated with 12C, 14N, 40Ar, 84Kr, and 130Xe MeV ions were studied as a function of the absorbed energy (fluence). For light ions (12C, 14N) the saturation of single F centers takes place at higher absorbed energy (5Â ÃÂ 1023Â eV/cm3) than that for 40Ar, 84Kr and 130Xe ions (â¼1023Â eV/cm3). The saturation concentration of F centers for 12C and 14N (2Â ÃÂ 1019Â cmâ3) is twice of that for the heavier ions. Further irradiation with light ions decreases concentration of F centers, presumably due to aggregation, whereas for heavy ions the saturation concentration remains approximately the same that can be explained by much stronger recombination losses within single tracks.
