Materials for radiation detection are critically important and urgently demanded in diverse
fields, starting from fundamental scientific research to medical diagnostics, homeland …

Millisecond crystal relaxation has been used to explain anomalous decay in doped alkali
halides. We attribute this slowness to Fermi-Pasta-Ulam solitons. Our model exhibits …

KCl: Sn 2+ phosphors were synthesized from aqueous KCl/SnCl 2 solutions. Solvents with a
molar ratio of KCl: SnCl 2= 1: M (M= 0− 5) were dissolved in de-ionized water. The optical …

A NaCl: Sn 2+ phosphor was synthesized from an aqueous NaCl/SnCl 2/HCl solution. The
optical properties of the as-synthesized phosphor material were investigated by diffuse …

Using two methods we show that a quantized discrete breather in a 1D lattice is stable. One
method uses path integrals and compares correlations for a (linear) local mode with those of …

Quantum states of a discrete breather are studied in two ways. One method involves
numerical diagonalization of the Hamiltonian, the other uses the path integral to examine …

We have previously presented evidence for the formation of breathers in doped alkali
halides subjected to a flash of UV light. Properties of these breathers, their phase space …

From experiments on doped alkali-metal halide crystals there is reason to believe that
localized, stationary lattice solitons, often called breathers, form and inhibit the crystal's …

Anomalous decay kinetics in the low-energy emission of KCl: Tl at 475 nm is detected in the
30–110 K temperature range. This emission has many characteristics of an AX emission …

A Jahn-Teller model, recently re-proposed in order to explain the anomalous slow emission
of impurity centers in alkali halides, can be supported on the basis of an analogy with the …
