Abstract
We demonstrate that several kinds of colored T centers can be prepared by an electrical coloring of Pb-doped KCl crystals. Ta is diamagnetic and it contains predominantly the [Pb-]2 species. Te is paramagnetic and we tentatively assign it to [Pb2]- units perturbed by Ca2+. Oxygen centers are thought to occur in Tb.
