A new mechanism for radiation damage processes in alkali halides

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...

Frenkel Defects in Alkali Halides

A Technique for Preparing Electron Trasparent Substrates of Alkali Halides

A new technique of preparing alkali halides electron transparent substrates has been developed. The substrate crystals are formed inside the holes of a carbon support film, so that each crystal has two free faces for deposition and study. The mechanism of formation of transparent crystals and the important factors involved have been discussed.

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...

F-CENTER ELECTRON QUANTIZATION IN ALKALI HALIDE CRYSTALS Background Alkali halides and alkaline earth halides are strongly ionic compounds

Alkali halides and alkaline earth halides are strongly ionic compounds that solidify as crystals. The name for the alkali elements (Li, Na, K, Rb and Cs) comes from the Arabic word alqili (ashes of the salt-wort plant that was once used as a source of sodium and potassium for making glass from sand). The name for the halogen elements (F, Cl, Br, I—and the rare radioactive element astatine) come...
