We report a resonant inelastic X-ray scattering study of Ni-substituted La{sub 2}CuO{sub 4}. Resonantly enhanced charge excitations are observed in 3-8 eV region when the incident photon energy is tuned to the Ni K-edge. The spectral weight shifts to higher energy loss as a function of the incident photon energy, which indicates that more than one excitation with different resonant conditions exists in the spectra. The lowest-energy excitation is located around 4 eV and is ascribed to the charge-transfer excitation from O 2p to Ni 3d.
