Various electron-spectroscopic results including core-level X-ray photoemission, X-ray absorption, Ce 3d-4f and 4d-4f resonant photoemission, and inverse-photoemission spectroscopy on the valence fluctuating ferromagnet CeFe2 are presented and analyzed with model calculations using the Anderson-impurity Hamiltonian. Surface effects on the spectra are taken into account in the analysis. The valence-band spectra are also compared with the band-structure density of states calculated using the local-spin-density approximation. The validity of describing the Ce 4f states as a localized impurity level and in the 4f band picture is discussed.
