      We present a rigorous parameter-free theoretical treatment of the   Ce 4s and 5s photoelectron spectra of CeO2. The currently   accepted model explains the satellite structure in the   photoelectron spectra in terms of mixed valence (Ce 4f0 O 2p6, Ce   4f1 O 2p5, and Ce 4f2 O 2p4) configurations. We show that charge   transfer (CT) into Ce 5d as well as configurations involving   intra-atomic movement of charge must be considered in addition   and compute their contributions to the spectra.
