Abstract
The nuclear reaction Li6 (n,α) H3 is the predominant cause of radiation damage
in single crystals of lithium fluoride when irradiated with thermal neutrons. The total range of the fission products is small (some 10-3 cm) so that the distribution of defects, created at one fission, is unlikely to be homogeneous in a macroscopic sample. With the assumption that an elementary volume per fission exists, which contains all the defects formed at one event, an order of its magnitude can be deduced from the obtained data. In the optical absorption spectrum taken on crystals which received a dose smaller than 1014 neutrons/cm2, the F-band is predominant. A study on its reproducibility
leads to the conclusion that the band formation depends on the previous history of the sample. A volume effect in the annealing of γ-irradiated LiF crystals is found.
