Popis: first-principles calculations based on density functional theory were performed,including XANES modeling and projected density-of-state simulations. A good agreement is obtained betweentheoretical and experimental polarized spectra. This enables us to assign the main XANES peaks in terms oforbitalhybridization.ThethoroughanalysisoftheCaC
