Description

The 5f-electron photoemission peak 1 eV below the Fermi energy E/sub F/ in UPd3 is generally assigned as a 5f2 yields 5f1 transition, consistent with other evidence of a stable U4+ valence state. We report resonant photoemission spectra for the system Y/sub 1-x/U/sub x/Pd3 which show that the peak narrows and shifts to the Fermi level as x decreases from 1. We hypothesize that the shift arises from a decrease in the Fermi energy as Y3+ replaces U4+, and therefore expect interesting changes in transport properties as E/sub F/ is tuned in this way
