Spectroscopic analysis of lithium terbium tetrafluoride

Terbium (lithium zinc) distannide, TbLi1–xZnxSn2 (x = 0.2)

The new terbium (lithium zinc) distannide, TbLi(1-x)Zn(x)Sn(2) (x = 0.2) crystallizes in the ortho-rhom-bic CeNiSi(2) structure type with space group Cmcm and Pearson symbol oS16. Of the four independent 4c atom positions (m2m site symmetry), three are fully occupied by individual atoms (two by Sn and one by Tb atoms) and the fourth is occupied by Li and Zn atoms with a statistical distribution...

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...

Spectroscopic determination of the s-wave scattering length of lithium.

E. R. I. Abraham, W. I. McAlexander, C. A. Sackett, and Randall G. Hulet Physics Department and Rice Quantum Institute, Rice University, Houston, Texas 77251-1892 (Received 2 September 1994) Two-photon photoassociation of colliding ultracold Li atoms is used to probe the Su sad ground state of Li2. The binding energy of the least-bound state of this triplet potential, y ­ 10, is found to be 12....

Optical properties of lithium terbium fluoride and implications for performance in high power lasers.

LiTbF4 has the potential to replace traditional magneto-optic garnet materials as a Faraday rotator in high power laser systems due to its high Verdet constant. New measurements are reported of the ordinary and extraordinary refractive indices of LiTbF4 as functions of wavelength and temperature, respectively, as well as their corresponding Sellmeier expressions. Consequently, the Verdet coeffi...
