Nature of the N b absorption band in LiF crystals
It was found by the methods of optical spectroscopy and X-ray diffraction analysis that the N b absorption band in LiF crystals is related to the reoriented F 4 center when all the F centers lie in the (110) plane. These defects are decomposed into F 2 centers at annealing.
