We have studied the 5f,6d electron states of the system USb/sub x/Te/sub 1-x/(100) using photoemission spectroscopy with synchrotron radiation. In contrast with the generally accepted picture of U chalcogenides and pnictides, we find the UTe that the main 5f level lies 0.75 eV below E/sub F/ rather than at E/sub F/ and that 6d states exist at E/sub F/. Our results may be explained with a model having a correlated quasilocalized 5f/sup 3-delta/ (delta = 0 -- 0.5) level resonant with broader 6d bands rather than bandlike 5f levels.
