Abstract

We present calculations for resonant inelastic x-ray scattering (RIXS) in edge-shared copper oxide systems, such as Li2 Cu O2 and CuGe O3, appropriate for hard x-ray scattering, such as the copper K edge. We perform exact diagonalizations of the multiband Hubbard model and determine the energies, orbital character, and resonance profiles of excitations which can be probed via RIXS. We find excellent agreement with recent results on Li2 Cu O2 and CuGe O3 in the 2-7 eV photon energy loss range.
