The O-ccntcr in CaFa is invcstisatcd by performing multiple scattcrirq Xa calculations on the (Ore)'-cluster. In agreement with cxpcrimcnt, a strong Jahn-Teller distortion of tctrqondl symmetry is prcdictcd. Finally the ground state electronic structure of the cluster is discussed.
The luminescence spectra of the diluted systems CszZrClb: Te4+ and Cs#Q,: Te4+ are reported at liquid-helium and room temperature. The shape of the excitation spectrum of the Te 4+ luminescence reveals a dynamic Jahn-Teller distortion in the excited state. At low temperatures the Te4+ emission shows
