Atomic hydrogen centres in LiF–H − and LiF–H − , Mg 2+ are studied by optical and ESR techniques. X‐irradiation of these crystals at 80 K leads to the formation of the H i o ‐centres which are thermally stable up to 110 K. After thermal annealing of the H i o ‐centres in LiF–H − , Mg 2+ crystals a new atomic hydrogen centre is observed which is interpreted as an interstitial hydrogen atom stabilized by a complex of the Mg 2+ ion and a positive ion vacancy (H i o (Mg)‐centre). Thermal decay of the (H i o (Mg)‐centres occurs at 430 K and leads to the formation of a hydrogen atom in the cation vacancy (H s,c o (Mg)‐centre).
