Abstract
UPS measurements analyzed in the light of XPS spectra yield some information about the inhomogeneous nature of the Sm surface mixed-valence state in amorphous LaSmAu alloys. In addition, the quasi-ionic character expected for these materials is clearly evidenced by the observation of the structure of the Au 5d statesKeywords
