Detailed analysis of 4d core x-ray photoabsorption spectra (4d-XAS) in CeO2 is made with the impurity Anderson model by incorporating the solid-state effect of hybridization between 4f and valence-band states into the atomic calculation of multiplet structures. The hybridization effect plays an essential role in the multiplet structure observed in the prethreshold region of 4d-XAS. The effect of the finite width of the valence band, as well as that of the core-hole potential, is discussed. The multiplet structures in - and -Ce are also calculated for the sake of comparison.
