    Uranium hydride films with the β-UH3 structure were successfully synthesized using reactive sputter deposition. Their composition can be modified, if cooling the substrate to 177 K, by incorporating Mo as alloying element, in analogy to bulk nanocrystalline (UH3)-Mo hydrides. The films were in detail studied by in situ XPS (4f, 5d, 6p, valence band), valence-band UPS, and BIS, revealing variations of electronic structure with respect to U metal, confronted with ab initio calculations. Although large scale features of the band structure are consistently explained and 5f states remain at the Fermi level EF, spectral features close to EF are not well reproduced by DFT or DFT+U calculations. This situation suggests prominence of electron-electron correlations affecting spectral function in the conditions of intermediate 5f localization.
