Title
Paramagnetic lead centers in electrolytically colored kcl-pb crystals

Abstract
Monomer and dimer paramagnetic lead centres have been identified for the first time by electron paramagnetic resonance (EPR) in electrolytically coloured low-purity KCl:Pb crystals. The monomer Pb-(Rh) centre, with orthorhombic symmetry and local axes [1(1) over bar0$], [001] and [110], decays completely in darkness and is produced by illumination with visible light. It seems to be related to, but is different from, the so-called Te centres identified in the same samples by their optical and magneto-optical spectra, as well as to the monomer Pb- centres earlier observed by EPR in high-purity KCl:Pb crystals x-ray irradiated at room temperature. The Tr1 and Tr2 trapped electron lead-dimer centres, with axial symmetry around [111], seem to be related to the Td centres identified by magneto-optical measurements.
