  We have performed angle-resolved photoemission spectroscopy (ARPES)
experiments on paramagnetic UFeGa5 using soft X-ray synchrotron radiation
(hn=500eV) and derived the bulk- and U 5f-sensitive electronic structure of
UFeGa5. Although the agreement between the experimental band structure and the
LDA calculation treating U 5f electrons as being itinerant is qualitative, the
morphology of the Fermi surface is well explained by the calculation,
suggesting that the U 5f states can be essentially understood within the
itinerant-electron model.
