X-ray-photoemission spectroscopy and bremsstrahlung-isochromat spectroscopy are utilized to examine the series of uranium silicides U3Si2, USi, USi2, and USi3. Maintaining the same ligand, this set of materials progresses from the case where direct f-f interaction is possible to one where only f-ligand interactions can occur. It is found that, while the results are dominated by the properties of the measurement techniques, there is evidence for f-band broadening with increasing ligand interactions.
