5f Resonant photoemission from plutonium

Experimental resonant photoemission (ResPes) results for alpha-Pu and delta-Pu bulk samples are presented and compared to the results of an atomic model calculation. Both Pu samples exhibit limited agreement with the atomic model calculations. As expected, alpha-Pu appears to have more 5f valence band delocalization than delta-Pu. Evidence of an enhanced sensitivity to surface corruption, by using synchrotron radiation as the excitation., is presented. (C) 2001 Elsevier Science B.V. All rights reserved.
