Abstract

Both U5f partial density of states (DOS) and partial DOS without U5f for UPd2Al3 and UC were experimentally obtained by using U5d-5f resonant photoemission technique. Both spectra are compared with the results obtained by the energy band calculation. From the comparison, the spectra of U5f partial DOS cannot be reproduced by the band calculation except for the Fermi edge structures. In contrast, the spectra of partial DOS without U5f states are reproduced well by those from ligands. These facts suggest that the spectra are not explained only by the band theory, but the correlation effect. S0368204896026990.
