Angle-integrated photoemission spectra from Ce24Co11 are presented in the region of the 4d-4f threshold (112-130 eV) and are interpreted in the frame of the impurity model. The constant-initial-state spectra with initial states in the two photoemission structures having 4f character (near the Fermi level and at -2.1 eV) are different across the 4d-4f resonance. The impurity model including 4d core levels of Ce gives excellent fitting of the constant-initial-state spectra; the dependence of the results on the parameters of the model is discussed.
