1. Local and nanoscale structure and speciation in the PuO(sub 2x-y)(OH)(sub 2y).zH2O system

Author

Abstract

Pu L3 x-ray absorption fine structure spectra demonstrate that although the Pu sublattice remains the ordered part of the Pu distribution, the nearest-neighbor O atoms even at x=o are found in a multisite distribution with Pu-O distances consistent with the stable incorporation of OH- into the PuO2 lattice.

Abstract

Pu L3 W-ray near edge absorption spectra for Pu(0-VII) for more than 60 chalcogenides, chlorides, hydrates, hydroxides, nitrates, carbonates, oxy-hydroxides and other compounds both as solids and in solution are reported.

3. Speciation and unusual reactivity in PuO (sub)2+x

Author

Conradson, Steven D., Begg, Bruce D., Clark, David L., Den Auwer, Christophe, Espinosa-Faller, Francisco J., Gordon, Pamela L., Hess, Nancy J., Hess, Ryan, Keogh, D. Webster, Morales, Luis A., Neu, Mary P., Runde, Wolfgang, Tait, C. Drew, Veirs, D. Kirk, and Villella, Phillip M.

Abstract

Research has been conducted on PuO (sub)2+x. The authors report that the number of oxo atoms increases when the samples are equilibrated with humid air, and indicate that Pu reactivity in this system differes from that of isolated complexes.
