Abstract :
The resonant inelastic X-ray scattering (RIXS) was measured for an insulating SrCuO2 with changing the incident photon energy (hν) near the Cu 1s absorption edge (K-edge). Complex structures and their dependences on the momentum transfer (Δk) and hν were observed. The hν dependence of the RIXS spectra measured for a constant Δk=2.4π has shown a remarkable enhancement near the absorption maximum and a shift of the spectral weight toward larger loss-energy with increasing hν. Also, the energies of the inelastic loss peaks in the RIXS spectra for the fixed excitation at 8.993 keV, i.e. 10 eV below the absorption maximum, have shown clear dependence on Δk. These results are in a qualitative agreement with a theoretical prediction.
