The relativistic formulas for x-ray-photoemission-spectroscopy (XPS) intensities are derived and used in calculations for UIr/sub 3/, UPt/sub 3/, and UAu/sub 3/. The densities of states and the potentials used to calculate the radial matrix elements were taken from fully relativistic self-consistent linear muffin-tin orbital (LMTO) electronic band-structure calculations. The calculated XPS intensities agree well with experimental XPS data for UPt/sub 3/ and UAu/sub 3/ (there are no XPS data for UIr/sub 3/). This suggests that the band-structure model for these heavy fermions is valid at room temperature and away from the Fermi energy, where the effects of the strong renormalization of the independent-electron properties that are presumably responsible for the exotic low-temperature anomalies seem to have little influence.
