The role of neptunium oxidation states and coordination in shaping XANES spectra at the Np L3 absorption edge
This paper presents the results of a comprehensive study of neptunium oxides in oxidation states +4 to +7 using X-ray absorption near-edge spectroscopy (XANES) and theoretical modeling. Based on labor...
