| Abstract: | The X-ray photoemission spectra (XPS) of the A15 type compounds V3Au, Nb3Os, Nb3Ir, Nb3Pt and Nb3Au have been studied. The inner level binding energies of the different components and the valence electron distribution were measured. The Nb4d and the X5d energy bands of the Nb3X compounds appear to be more and more separate with increasing atomic number of the X component. The comparison between the results from X-ray emission spectroscopy (XES) and X-ray photoelectron spectroscopy (XPS) of corresponding V3X and Nb3X compounds points out the similarity of their electronic structures. |
