A thorough investigation of F → X conversion in NaCl crystals heat‐treated at different temperatures as well as the results of the high‐temperature X‐irradiation made it possible to conclude that there exist two types of X‐centres which differ in the formation sites. X‐centres localized in the crystal lattice (X L ‐centres) are responsible for the absorption band with the peak position at 620 nm, while X‐centres responsible for the 550 nm band are localized along dislocation lines (X D ‐centres).
