relevant to the Earth’s lower mantle. Therefore, (nonresonant) Kβ1,3 and valence-to-core X-ray emission spectroscopy as well as resonant 1s2p X-ray emission spectroscopy were utilized. First, the study of [...] Furthermore, the emergence of low-wavenumber Raman bands in a wavenumber range between 100 cm−1 and 350 cm−1 could be assigned to Fe4C4O13. Second, the study on cold compressed Fe2O3 verifies a two-step [...] the interpretation of Kβ1,3-spectra in the future. Additionally, the setup for spectroscopic measurements was significantly improved with reduced data acquisition times of Kβ1,3 X-ray emission spectroscopy …
