An ESR study of vanadium-doped paratellurite indicates that vanadium enters the lattice as V4+, equally populating the four inequivalent cation sites. The 3d1 electron exhibits hyperfine interaction with the I=7/2 51V nucleus and superhyperfine inter

The discovery of the fast decay time of pure CsI and the various results of the measured samples led us to investigate the decay time of CsI crystals prepared by different methods. Carefully grown or prepared pure CsI behaves as fast (ns range) scint

In zinc tungstate single crystals grown in platinum crucibles, a new platinum-impurity center was observed by ESR showing C 1 symmetry below 26 K and C 2 symmetry above 50 K. The Pt impurity resides as Pt 3+ in a Zn 2+ lattice site where reduction to

In undoped paratellurite ( alpha -TeO2) electron-irradiated near room temperature, in addition to the VO. centre, two further intrinsic, strongly anisotropic radiation defects have been characterised using ESR and ENDOR spectroscopy. The first new ce

The ESR spectrum of paratellurite (\ensuremath{\alpha}-${\mathrm{TeO}}_{2}$) exposed to 1-MeV electron irradiation reveals a single spin-(1/2) defect in eight inequivalent sites with an anisotropic g value close to the free-electron value. Principal

Bismuth germanate Bi4Ge3O12 single crystals with constant diameters were grown in a phantom controlled Czochralski growth apparatus. Some irregularities such as the tendency of spiral instead of cylindrical growth were observed. Some interpretation o
