An alternative model of the Nc-center as a complex defect consisting of the F 2 + -center perturbed by the FL defect (where FL is Li0 in the F-center) is confirmed by the methods of optical spectroscopy and X-ray diffraction analysis of LiF crystals. Upon selective optical excitation, these centers are decomposed into F2 and FL defects.
