WebHere, we present a detailed comparative study of Sc K-edge XANES spectra of three Sc-bearing compounds: a garnet (Ca 3 Sc 2 Si 3 O 12 ), an oxide (Sc 2 O 3) and a phosphate (ScPO 4 ·2H 2 O). First-principles calculations have been performed to interpret the origin of the K pre-edge spectral features. Web13 apr. 2024 · Log in. Sign up

Web8 oct. 2012 · The authors propose a K-edge imaging optimization model to determine these two energy bins. Methods: K-edge image contrast with spectral CT depends on the specifications of the two energy bins on both sides of a K-edge in the attenuation profile of a relatively high atomic number material. The wider the energy bin width is, the lower the … WebbDepartment of Physics and Astronomy, SUNY-Stony Brook, Stony Brook, NY 11794, USA.
