The Fe 2p spectra of silicate minerals were measured. The Fe 2p32 binding energy of Fe(III) ion in andradite was 712.3 eV, whereas those of Fe(II) ions in other minerals (olivines, almandine and orthopyroxene) were 710.4–710.8 eV. The characteristic satellite structures were observed in ...
We systematically investigated the L-edge X-ray emission spectroscopy (XES), a 3d-to-2ptransition, of Fe2+- and Fe3+-bearing MgSiO3 perovskite under high pressure based on the internally consistent LSDA+Utechnique combined with the Slater-transition method. The Fe L-edge XES spectra can be ...
