Silicon Tetrafluoride on Io
Silicon tetrafluoride (SiF4) is observed in terrestrial volcanic gases and is predicted to be the major F – bearing species in low temperature volcanic gases on Io (Schaefer and Fegley, 2005b). SiF4 gas is also a potential indicator of silica – rich crust on Io. We used F/S ratios in terrestrial and extraterrestrial basalts, and gas/lava enrichment factors for F and S measured at terrestrial vo...
متن کاملTrisodium scandium bis(orthoborate)
Single crystals of tris-odium scandium bis-(orthoborate), Na(3)Sc(BO(3))(2), have been obtained by spontaneous crystallization from an Na(2)O-Sc(2)O(3)-B(2)O(3) melt. The crystal structure features a three-dimensional framework composed of planar [BO(3)](3-) groups and distorted ScO(6) octa-hedra with Na atoms in the cavities. The Sc atom occupies a special position (Wyckoff position 2b, site s...
متن کاملGadolinium scandium germanide, Gd2Sc3Ge4
Gd(2)Sc(3)Ge(4) adopts the ortho-rhom-bic Pu(5)Rh(4)-type structure. The crystal structure contains six sites in the asymmetric unit: two sites are statistically occupied by rare-earth atoms with Gd:Sc ratios of 0.967 (4):0.033 (4) and 0.031 (3):0.969 (3), one site (.m. symmetry) is occupied by Sc atoms, and three distinct sites (two of which with .m. symmetry) are occupied by Ge atoms. The rar...
متن کاملHyperfine splitting in lithiumlike scandium
High-precision experiments on the ground state hyperfine splitting in highly charged ions performed at the GSI facilities and at the EBITs (see, e.g., Refs. [1, 2, 3]) have triggered intensive theoretical investigations of this effect. The error bars of the theoretical hyperfine splitting values are mainly determined by the nuclear magnetization distribution correction, the so-called Bohr-Weiss...
متن کاملTrilithium scandium bis(orthoborate)
Single crystals of the title compound, Li(3)Sc(BO(3))(2), have been obtained by spontaneous nucleation from a high-temperature melt. The title compound adopts a framework structure and is composed of distorted [ScO(6)] octa-hedra, [LiO(4)] tetra-hedra, [LiO(4)] recta-ngles and isolated [BO(3)] triangles. Except for the Sc and one Li atom (both on inversion centres), all atoms are in general pos...
