Abstract
We report on the Cu resonant inelastic x-ray scattering (RIXS) of Cu-O one-dimensional strongly correlated insulator systems with contrasting atomic arrangements, namely edge-sharing and corner-sharing . 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.
