An investigation was conducted on the colored layers in LiF monocrystals produced by bombardment with 13.5 Mev deuterons. In specimens grown in a high vacuum and irradiated with approximates 1.5 x 10¹³ deuterons, absorption bands appeared at 248, 316, 378, 145, 550, 780, and 950 μmm. After irradiation the colored layer was removed in 34 steps and the absorption spectrum measured after each thickness decrement of 0.2 and 1 μmm. A description is given of a new method used to measure the thickness of the colored layers of the strongest bands at 248 μmm (F-band), 445 μmm (M-band), 316 μ mm (R₁- band), and 378 μmm (R/sub 2/band). No qualitative difference was found in the spectra at different sample depths. Assuming that the secondary processes are insignificant, the mean coloration depth (defined as the value at which the change of extinction reaches half the maximum value) is equal to the mean penetration depth of the deuterons. The mean coloration depth of the F-, M-, R₁-, and R₂-bands was determined to be 0.655 plus or minus 0.001 mm. A relationship was established between the thickness of the colored layer and the penetration depth of the deuterons. (AID Press, Vol. 2: No. 180, March 1964)
