Abstract

The measurement of resonant inelastic x-ray scattering (RIXS) in a variety of layered cuprates at the copper (CU) L₃ edge was done where rayleigh scattering was negligible because of the very strong absorption resonance. The insulating compounds such as CuO, La₂CuO₄, and the optimally doped superconductors such as La_1.85Sr _0.15CuO₄ were used for measurement. Both the dd and charge transfer excitations were present in all the spectra and the reproduction of the dd-excitation peak was done using simple crystal field model. The RIXS at the L₃edge was demonstrated because of the resonance strength and 2p spin-orbit splitting.
