F-center profiles created in LiF with 56 MeV α-particles and 28 MeV deuterons are obtained at room temperature by an optical method using a micro-spectrophotometer. These profiles are in a good agreement with the calculated electronic stopping power but a departure from linearity above 1014 MeV/cm3 is observed. A saturation effect related with the dose is also observed and the F-center production is slightly lower, in the case of samples irradiated in the (110) direction, than in the (100) one. Taking into account the interaction tubes with F-centers, F-aggregate centers and cationic defects, we can give an interpretation of our results.
