    Notes: Summary The structural and surface sensitivity of electron energy loss spectroscopy has been exploited to investigate the Pd-Si(111) 2×1 interface. We found the twoM iv,v shallow edges of Pd suitable for an EELS study on the whole coverage range. EXAFSlike oscillations were detectable above theM iv,v edge for about 150 eV. These features together with the intensity ratio (M v/M iv) between theM v andM iv components showed a reproducible dependencevs. the thickness of the Pd film. From the analysis of the near edge part and the EXAFSlike oscillations a general indication of the formation of a compound very close to Pd2Si in the coverage range (5÷20) Å and the presence of a peculiar Pd−Si compound at coverages lower than 5 Å was obtained.

    Notes: Abstract The electronic structure of small chromium clusters deposited by evaporation onto clean polycrystalline graphite has been studied by means of the Electron Energy Loss (EELS), Auger and X-ray photoemission (XPS) spectroscopies. The XPS results show an increase of the binding energy of both core levels and 3d valence band states when the cluster size decreases. The analysis of the Auger spectra by the Cini-Sawatzky theory suggests that the electronic screening properties do not change in small clusters with respect to the bulk. The EELS spectra indicate an increase of the energy loss features due to the interband transitions between 3d full states andsp empty states when the cluster size decreases. These observations are attributed to sizeable changes occurring in the electronic structure of the clusters.
