X-ray absorption near-edge spectroscopy of plutonium solid species.

PDF Version Also Available for Download.

Description

We present XANES at the L{sub III} edge for four plutonium solid phases: Pu(III)F{sub 3}, Pu(IV)O{sub 2}, NaPu(V)O{sub 2}CO{sub 3}, and Ba{sub 3}Pu(VI)O{sub 6}. These correspond to the four important oxidation states in the process chemistry and environmental chemistry of plutonium. By a fitting method that uses an arc tangent function and gaussian curves, it was possible to reproducibly determine the edge energy and distinguish among the four oxidation states. These data demonstrate a 1.85 {+-} 0.20 eV shift per oxidation state.
