- 論文の詳細を見る
Single crystals of lithium fluoride have been irradiated with deuterons or protons at liquid nitrogen temperature. In absorption spectra of the crystals immediately after irradiation, a band is observed at 542 nm in addition to the F and M bands. This band has an almost constant intensity during warming from LNT to RT. It is obscured by the other overlapping bands when the crystal is heated about 100℃ or when this is aged at RT for a long time. The nature of this band is examined in connection with the so-called N_2 band, Ferge's I band and Vander Lugt's N_c band. The following relation is believed to be most plausible: The observed absorption band is identified with the I band. The N_2 band is identified with the N_c band but may not be identified with the I band.
