The experimental result of resonant inelastic X-ray scattering in LaCuO is theoretically analyzed. The ground state of the system is described within the Hartree-Fock approximation, and the electronic excitation processes are taken account of within the random phase approximation. In the experiment, the spectral shape shows a strong dependence on the transferred momentum of the photon. We have succeeded in reproducing theoretically this dependence quantitatively.
