    A trigonal color center in NaF

    Uniaxial stress splitting experiments suggest the 5456 Å zero-phonon line in NaF to be due to a transition of the F 3 + center. The line and a number of phonon...

    Farbzentren rhombischer und monokliner Symmetrien in NaF

    A number of zero-phonon absorption lines ofF aggregate color centers is studied inx-irradiated NaF crystals under uniaxial stress. The color centers associated with the lines are found to exhibit rhombic (D2h, D2

    Gitterfehlordnung in KCl mit Farbzentren

    Color centers were created in KCl single crystals by additive coloration and X-irradiation at room temperature. Change of lattice parameter was determined by an X-ray method and change of mass density by a hyd...

    Pseudo Stark and uniaxial stress splitting of the 6955 Å zero-phonon line in LiF

    Pseudo Stark and uniaxial stress splitting is observed with the zero-phonon line 6955 Å in LiF at 4.2 °K. From the combination of the results obtained by means of both methods it is concluded that the correspo...

    Momentenanalyse derR 2-Nullphononen-Linie in NaF unter einaxialem Druck

    The R2 zero-phonon absorption line 4480 Å in NaF at 4.2 °K and 23 °K is studied under uniaxial stress along 〈100〉 and 〈100〉. According to the F3 model of theR center the R2 line is found to be due to a transition...

    Gitterkonstanten- und Dichteänderung durchF-Zentren in KBr

    F centers were created in KBr by additive coloration. Change of lattice parameter was determined by the X-ray diffraction method and change of mass density by a hydrostatic flotation method. Combination of thes....

    Reststrahlspektrum und Eigenabsorptionskante von CdxCa1−xO

    The reflectivity of CdxCa1−xO mixed crystals prepared by sintering has been measured at 300 °K from 0.2 to 47μm. The Reststrahlenbands show the expected “one-mode” behavior. By Kramers-Kronig-analysis, the longit...

    Optische Plasmaresonanz in CdO

    The plasma resonance in semiconducting CdO with different electron concentrations has been investigated by means of reflectivity measurements on thin films with metallic substrate. The results — especially the...
