摘要: A descriptive account is given of our most recent research on the actinide dioxides with Advanced Light Source Molecular Environmental Science (ALS-MES) Beamline 11.0.2 soft X-ray scanning transmission microscope (STXM) at Lawrence Berkeley National Laboratory (LBNL). The ALS-MES STXM permits near-edge absorption fine structure (NEXAFS) and imaging 30-nm spatial resolution. first spectromicroscopy NEXAFS spectra 4d5/2 edges imaged transuranic particles, NpO2 PuO2, have been obtained. Radiation damage induced by was observed in investigation a mixed oxidation state particle (Np(V,VI)) minimized during collection actual edge Np(V,VI) solid. plutonium elemental map obtained from an irregular PuO2 dimensions 650 × 650 nm. Pu were collected several different locations identical. representative oxygen K-edge spectrum UO2 resembles bulk material. unique current performance extremely low energies (ca. 100 eV) that may permit successful measurement 5d documented. Finally, potential as tool for investigations briefly discussed.
