Multielectron excitations in the K -edge x-ray-absorption near-edge spectra of V, Cr, and Mn 3 d0 compounds with tetrahedral coordination. Bianconi, A., Garcia, J., Benfatto, M., Marcelli, A., Natoli, C. R., & Ruiz-Lopez, M. F. Physical Review B, 43(9):6885–6892, March, 1991.
Paper doi abstract bibtex Multielectron excitations involving metal deep 1 s and shallow 3 p core levels have been identified in the x-ray-absorption spectra in the range 50†” 60 eV above the K edge of transition-metal ions V, Cr, and Mn with tetrahedral coordination geometry. The many-body transitions have been found after subtraction of the dominant one-electron transitions to continuum states giving the x-ray-absorption near-edge structure. The presence of many-body excitations involving valence electrons has been found at ∼7 eV above threshold. The energy positions are in good agreement with calculated excitation energies for the many-body configurations, where the two excited electrons are in the unoccupied molecular t 2 * orbital. Experimental comparison of the intensities of corresponding many-body satellites between the Cr 2 p x-ray photoelectron spectrum and Cr K-edge absorption spectrum is reported for K 2 CrO 4 .
