摘要：

High-resolution resonant inelastic x-ray scattering (RIXS) spectra from CuO in the 1s2p emission region were measured. A surprisingly complicated set of spectra was observed. Detailed analysis of these spectra reveals the existence of an excited state, which is hidden in the Cu-K x-ray absorption spectrum of CuO. Furthermore, the energy of this excited state corresponds well to a Cu 4p(z)-like state predicted by a real-space multiple-scattering technique, but has not been observed experimentally up to now. This result demonstrates the potential use of RIXS to complement x-ray absorption spectroscopy.
