WitrynaAb initio perturbed ion cluster-in-the-lattice calculations of the impurity centers NaI:Tl + and CsI:Tl + are presented. We study several active clusters of increasing complexity and show that the lattice relaxation around the Tl + impurity implies the concerted movement of several shells of neighbors. The results also reveal the importance of … Witryna(1) other quantitative measurements can follow the scheme of impurity testing, if the working range is . 65. close to the detection or quantitation limits of the technology, …
