摘　　要：The electron spin resonance, transmission and reflection spectra showed that a steadily electron-type paramagnetic complex color point defect Fn center is produced by 60Co γ-ray strong dose irradiation in a single crystal LiF. The γ-ray irradiation dose is too large to recognize any character peak of F2, F2, F2, and F3 centers in the transmission and reflection spectra of the single crystal. LiF: Fn is opaque when wavelength is shorter than about 750nm and has not refiection when wavelength is shorter than about 800nm. The Fn center has a wide ESR peak with ΔBpp of 8 millitesla and the effect g-factor is 1.998±0.002.The electron spin resonance, transmission and reflection spectra showed that a steadily electron-type paramagnetic complex color point defect Fn center is produced by 60Co γ-ray strong dose irradiation in a single crystal LiF.
