In LiF:OH crystals neutron‐irradiated at low temperatures a new ESR absorption is observed after thermally annealed and aged at room temperature for some time. From the analysis of the ESR spectra the absorption is identified to be due to interstitial hydrogen atoms (H 0 1 centers) grown in LiF crystals during aging. This hydrogen center is unusually stable and decays very slowly even at room temperature. The ESR absorption lines of this center broadens at low temperatures. The ( g ‐factor, proton hf constant and shf constants are determined from the spectra obtained at room temperature measurements.
