Abstract

We report on the Cu 1s resonant inelastic x-ray scattering (RIXS) of Cu-O one-dimensional strongly correlated insulator systems with contrasting atomic arrangements, namely edge-sharing CuGeO₃ and corner-sharing Sr₂CuO₃. Owing to good statistics of the high-resolution RIXS data, so far unresolved fine structures are revealed. Detailed photon-energy and momentum dependence of the RIXS spectra in comparison with theoretical calculations has clarified the natures of the low-energy charge excitations and hybridization of the electronic states.
