RADIATION EFFECTS IN LiF CRYSTAL. Report 14

Technical Report ·
OSTI ID:4062722
The lattice parameters and the optical absorptions of LiF single crystnls which were irradiated with neutrons of 2 x 10/sup 1//sup 7/ nvt and isothermally annealed at successively higher temperatures up to 800 deg C were measured at room temperature. The microscopic observatioms were also carried out. The steps in the recovery curve of lattice parameter vs. annealing temperature remarkably correspond to the increase and decrease of the M-band and F-band (colloidal) and the last step corresponds to the formation of the cavities in the crystal which appear to have a close connection with the dislocation network in the crystal.
