X-Ray Photoemission Spectra of 4d and 3d Electrons in Lanthanum- and Cerium-Halides

X-ray photoemission spectra have been measured of the 4d and 3d shells of La 3+ and Ce 3+ in La- and Ce-halides. The results, particularly in the case of the spectra of the 4d level, show a marked dependence of spectral profile of halogen. The existence of the satellite accompanying the 4d 5/2 and 4d 3/2 components is shown by an analysis of the spectra obtained by deconvolution of the raw data of La-halides. The halogen dependence of the spectra is ascribed to the simultaneous charge transfer transition from the valence level of ligand to the unoccupied 4f level of the metal ion as being the orgin of the satellite.
