摘要: Uranium is a member of Actinides and plays important role in nuclear science technology. Electronic structural investigations actinide compounds attract major interest science. The electronic structure chemical bonding coffinite USiO4 are investigated by X-ray Absorption Fine Structure spectroscopy (XAFS). U L3- edge absorption spectrum compared with L3-edge spectra UO2 UTe due to their different structures. study presents XANES (x-ray Near-Edge Structure) Extended XAFS (EXAFS) calculations thin films. full multiple scattering approach has been applied the calculation L3 USiO4, UTe, based on choices one electron potentials according coordinations using real space method FEFF 8.2 code.
