Ground-state properties of heavy alkali halides

Magneto-optical properties of the excited state of F centres in some alkali-halides

The orbital g-factor and the spin-orbit splittings of the first excited state of F-centres are measured in NaCl, NaBr, KBr and KF crystals by observing absorption and magnetic circular dichroism at various temperatures and using the moments method. Our experimental results and others are compared with Harker’s theoretical values. LE JOURNAL DE PHYSIQUE TOME 38, OCTOBRE 1977, Classification Phys...

Frenkel Defects in Alkali Halides

Complex metal halides in fused alkali nitrates

The results of this investigation have provided additional information by chemical methods of the extent of association in fused salts. Association effects observed in solubility and rate studies in fused alkali nitrate are shown to be consistent with the assumption that complex ions such as those existing in aqueous solutions are formed between metal ions and halide ions. In addition, the rate...

Excitons and Radiation Damage in Alkali Halides

The quantum mechanical description of atomic spectra was the beginning of a new era of quantum physics which today is the theoretical basis of nuclear and solid state physics, chemistry, and biochemistry [1,2]. Quantum mechanics opened also a new look to solid state physics which will be illustrated by the development of the conception of excitons [3]. One of the basic quantum mechanical proble...

Detailed Study of the Electron-phonon Interaction in Alkali Halides” Part Ii Transmission Secondary Emission from Alkali Halides

The phenomenon of secondary emission from alkali halides is studied in transmission. This allows the variation of one more parameter (thickness) than in conventional reflection studies. An empirical method based on published results of scattering by thin foils is used to determine the spatial dependence of the internal electron excitation function. The results of the Monte Carlo calculations pr...
