The group systematically investigates the electronic and coordination structures of actinide (An) and chemical homologue lanthanide (Ln) systems with novel synchrotron-based high energy resolution X-ray emission/absorption/inelastic scattering techniques. The experimental results are supported by theoretical calculations and simulations with quantum chemical codes. These investigations improve our understanding of An/Ln reactivity in repository systems and waste matrices on a molecular scale and thereby contribute to the assessment of the repository long term safety. The elucidation of electronic and coordination structures of An/Ln systems provides basic insight into structure-reactivity relationships of actinide elements, which is still a challenging scientific frontier. The group was initiated in July, 2011 - Helmholtz Young Investigators Group grant (VH-NG-734) awarded by the Helmholtz Association of German Research Centers (HGF) and the Karlsruhe Institute of Technology (KIT), Faculty of Chemistry and Biosciences, Institute for Nuclear Waste Disposal (INE).

The ACTINIDE BOND properties in gas, liquid and solid state
https://cordis.europa.eu/project/id/101003292
Description of the project:
Understanding the electronic structure and chemical bonding properties of the early actinide (An) elements (Th-Cm) poses a great challenge and frontier in fundamental chemistry and physics. We aim to clarify the link between covalency and strength of the chemical bond of the early An elements from Th to Cm in gas, liquid and solid state materials - combining innovative high challenge experimental setups, advanced synchrotron based spectroscopy methods and state-of-the-art quantum chemical computations. The RIXS and HR-XANES methods probe the occupied and unoccupied parts of the valence band with extraordinary energy resolution and, when combined for the metal and the ligand, unique information on the chemical bond can be obtained. We will gain a deep understanding of the An bond formation mechanisms and will develop spectroscopy methodologies with high potential for a breakthrough in efforts, e.g., to select ligands and An materials with specific characteristics. Ligands and materials with tailored properties are needed for example for developing advanced pharmaceutical compounds for targeted cancer treatment. A deep insight into the An electronic structures is also essential for developing innovative spent nuclear fuel matrices and to understand actinide environmental behaviour e.g. in contaminated sites. The new spectroscopy approaches are also expected to boost the advances of quantum chemical theoretical methods. Those are most challenged by the An atoms due to their large number of valence electrons and prevailing influence of relativistic effects in their electronic structure behaviour.

The Instrumentation
The utility of high energy resolution X-ray absorption near edge structure (HR-XANES), X-ray emission (XES) and resonant inelastic X-ray scattering (RIXS) spectroscopy techniques in studies of An elements was the motivator for installing and commissioning a multi-analyzer Johann type X-ray emission spectrometer (MAC-spectrometer, see the figure above) at the . INE-Beamline for actinide research at the KARA synchrotron radiation facility, Karlsruhe, Germany. The MAC-spectrometer is ultimately destined to be the central instrument at the radioactive end station of the newly constructed beamline for catalysis and actinide research (CAT-ACT-Beamline, beginning operation in 2016). The MAC-spectrometer is an adapted design of the XES spectrometer at the ID26 Beamline, ESRF, Grenoble, France, containing five spherically bent analyzer crystals with 1 m bending radius. Our set-up is optimized for An M4,5 edge HR-XANES and XES/RIXS experiments; absorption of 3-4 keV photons by air is minimized by a He environment enclosing sample, crystals, and detector, thereby enhancing efficiency. This instrument, combined with access to the controlled area laboratory at INE in close proximity, is worldwide unique, enabling An M4,5 edge HR-XANES and XES/RIXS investigations of solid and liquid phase radioactive materials, including those under extreme conditions. The Figure1 depicts the Np M5 edge HR-XANES spectra of 83 or 1 ppm Np sorbed on the clay mineral illite. The newly installed cryostat, possible to use down to 3 keV incident X-ray energy, is also shown.
