Title
$Cd^{+}(5s^{1})$ centres in $Rb_{2}ZnCl_{2}$ single crystals

Abstract
 Electron paramagnetic resonance and optical absorption spectra attributed to 5s(1) trapped electron Cd+(I) and Cd+(II) centres are observed over a broad temperature range in Rb2ZnCl4 single crystals doped with cadmium, after X-ray irradiation at 80 K and room temperature, respectively. The low temperature Cd+ (I) centre, which seems to be a substitutional Cd+ ion in a Zn2+ site, transforms into a Cd+ (II) centre at 190 K by trapping an anion vacancy, which has become mobile at this temperature, in its nearest-neighbour positions. The suggested structural models of the Cd+ centres are supported by the analysis of the spectral data considering covalency effects.
