Abstract
In alkali halides the excitons are responsible for any energy conversion processes by optical excitation in the fundamental absorption band or by irradiation with charged particles or X-rays with various excitation energy densities. Exciton processes determinate also both luminescence and defect creation under heavy ion irradiation with an extremely high excitation energy density of 103 eV/Å. The heavy ion track in LiF crystals consist of lithium atom aggregates in the central part (with a radius of r lat ≤20 Å) and single color centers in the extended lateral track region.
