Abstract : The evolution with temperature of the cerium 3d and 4d core levels in CePd 3 has been studied by X-rays Photoemission Spectroscopy XPS. Whereas the bulk experiments lattice parameter, X-rays absorption, inelastic neutron scattering

. indicate an increase in the cerium 4+4f0 5d2 configuration as the temperature decreases, our XPS results show on the contrary a complete disappearance of this cerium 4+ configuration.

Keywords : cerium alloys lattice constants mixed valence compounds palladium alloys X ray photoelectron spectra
