Strong irradiation of NaCl crystals results in a formation of sodium colloids which exhibit metallic properties. In consequence, besides the Na-23 line of NaCl a second well-separated Na-23 line occurs in the NMR spectrum caused by the Knight shift o

In this contribution we will consider some of the characteristic effects associated with the formation of radiation damage in NaCl. This work is directly related to the problem of the disposal of high level nuclear waste. For this reason, we will dis

The ionic conductivity of dilute Sr 1 −xYb x F 2 +x solid solutions has been studied as a function of temperature. For the migration enthalpy of fluoride interstitials the value 0.946 eV is obtained, and the value 0.56 eV for the dissociation entha

IR studies on localized vibrations of hydride ions in SrCI2 and SrF2 are reported. In hydrogenated and deuterated samples doped with trivalent rare earth ions two different axially symmetric complexes giving rise to two doublets are observed. For SrC

In this paper we report about the results of EPR and ionic thermocurrents (ITC) experiments on cubic solid solutions of the type Sr 1- x Eu x F 2+ x . A part of the Eu-ions is in the divalent state; these ions can be detected easily with EPR. From th

The shape of the potential energy well of ${\mathrm{Mn}}^{2+}$ as impurity in a number of alkaline-earth oxides is calculated, using the method of Hatcher and Dienes, for a polarizable-point-ion model. Potentials for the Mn-O, Ca-O, Sr-O, and Ba-O re

The optical properties of X-irradiated CaF2:Ni and SrF2:Ni are studied. An absorption band at 255 nm in CaF2 and 270 nm in SrF2 is created by X-irradiation. It is concluded from optical bleaching experiments in low-temperature X-irradiated samples th

EPR-spectra of X-irradiated “oxygen-poor” calciumchlorapatite single crystals have been analysed. The spectra can be associated with a new type of (OCl)2−molecular ion. The magnetic parameters deduced from rotational EPR experiments are compare

The results are given of EPR experiments on electron excess color centers in X-rayed synthetic calciumchlorapatite which is doped with fluoride ions. A comparison of the results obtained with those given in earlier papers on color centers in calciumc

In this paper we present results of an investigation of cubic ${\mathrm{Gd}}^{3+}$ ions in solid ${A}_{1\ensuremath{-}x}{R}_{x}{\mathrm{F}}_{2+x}$ ($A$ is an alkaline-earth ion and $R$ is a rare-earth ion) solutions. The values of $x$ were chosen bet
