An opportunity to define important trends in actinide covalency and relativistic expansion

This fully funded 3.5-year PhD studentship is available for an outstanding and ambitious student to undertake fundamental research into actinide electronic structure and magnetism. The selected candidate will apply state-of-the-art synchrotron X-ray spectroscopy techniques, including resonant inelastic X-ray scattering (RIXS) methods. RIXS is transforming our understanding of structure/function relationships by providing insights into how electronic structure and bonding relate to chemical reactivity, superconductivity and magnetism. Recently, RIXS methods have become available for the study of actinides. Unlike other areas of the periodic table, RIXS of actinides is still rather underdeveloped. Recently, we published a uranium 3d4f RIXS study (J. Am. Chem. Soc. 2024, 146, 32, 22570) showing the method has a distinct sensitivity to 5f radial expansion and is therefore a probe of covalency and relativistic effects. This studentship will apply the RIXS method we have developed beyond proof-of-principle, including studying novel molecular compounds synthesised by our collaborators within the University of Manchester Centre for Radiochemistry Research. The results will advance our understanding of trends in actinide ligand bonding and the influence of relativistic effects on actinide valence electrons.

The project will involve visits to international synchrotron radiation facilities including at Diamond Light Source (Oxfordshire), the European Synchrotron Radiation Facility (Grenoble) and Synchrotron Soleil (near Paris). X-ray spectroscopy measurement results will be analysed in Manchester and compared against the latest theoretical models.

The candidate will be trained to handle low-level radioactive and air-sensitive samples and a nuanced understanding of actinide electronic structure will be obtained, skills which are highly sought after within the nuclear industry. The student will develop X-ray spectroscopy measurement and analysis procedures, with the expectation that they will be internationally leading in the use of these methodologies by completing the PhD. In parallel the student will become accomplished in theoretical computation of electronic structure, bonding and the simulation of spectra. The student will become familiar with basic computer programming for writing their own analysis code for automated data reduction. The student will learn how to design experiments and write impactful scientific publications.
