Abstract
The electronic structure of the ternary CeTIn (T = Ni, Cu, Pd, Au) compounds was investigated by means of X-ray photoelectron spectroscopy. Our interest was aimed mainly to the valence bands and the Ce3d core levels of investigated compounds. Analysis of the valence bands indicates that they are mainly determined by the Tnd band, whereas a share of the R4f states can be estimated to be about a few percent only. The analysis of the difierential valence bands spectra between CeTIn and LaTIn analogues suggests that the Ce4f 1 ground states shift deeper below the Fermi level with an increase in the 4f level occupation factor. The analysis of the ⁄ £
