We research on the 5 electronic states of uranium compounds by soft-Xray angle-resolved photoemission spectroscopy (SX-ARPES) at BL23SU beamline in SPring-8. The ARPES in soft X-ray region is suitable for uranium compounds because the spectra well reflect the bulk-5 electronic states. We first succeeded in three-dementional mapping of 5-electronic states on UB
by measuring both angle (
) and photon energy (
) dependence of the photoemission. The band structures and Fermi surfaces are in good agreement with those by LDA calculaiton. In adittion, we observed the temperature-dependent change of the 5 band structure on antiferromagnetic superconductor UPd
Al
, suggesting that the 5 electrons change from localized to itinerant states as the temperature decreases.
