The U 5f states in the heavy fermion uranium compound UPd2Al3, studied by resonant and X-ray photoelectron spectroscopy

Abstract We have measured the X-ray photoemission and X-ray bremsstrahlung isochromat spectra of UPd 2 Al 3 , and compared with the results of the band structure calculation. The near E F part of the spectra are well reproduced by the calculated U 5f density of states, although the experimental spectra are broader than the calculations. These results suggest that the band structure calculation is a good starting point for the understanding of these spectra, although the spectra are not entirely understood by the calculations.
