6. Quantum Nuclear Dynamics in Resonant X-ray Scattering of Gas-Phase and Liquid Systems
Sammanfattning : This thesis focuses on the role of the nuclear degrees of freedom in X-ray induced molecular processes. An important part of it is devoted to establishing theoretical principles to model and interpret high-resolution resonant X-ray scattering experiments in gases and liquids. LÄS MER
7. Soft X-ray Scattering Dynamics Close to Core Ionization Thresholds in Atoms and Molecules
Sammanfattning : In this Thesis studies of highly excited states in gas-phase atoms and molecules (He, Ne, N2, O2, N2O and CO2) using a variety of synchrotron-radiation based techniques are presented. The three techniques used most frequently are X-ray-emission-threshold-electron coincidence (XETECO), X-ray emission spectroscopy (XES) and X-ray photoelectron spectroscopy (XPS) and they are all given a brief introduction.

8. Resonant Inelastic X-ray Scattering of Rare-Earth and Copper Systems
Sammanfattning : Rare earths and copper systems were studied using X-ray absorption spectroscopy (XAS) and resonant inelastic X-ray scattering (RIXS). The use of monochromased synchrotron radiation and improved energy resolution for RIXS made possible to obtain valuable information on the electronic structure in 4f, 5f and 3d systems. LÄS MER
9. Resonant Inelastic X-ray Scattering Studies on Quasi-Two-Dimensional Superconducting Materials
Sammanfattning : Unconventional superconductivity is one of the many fascinating research areas of condensed matter physics. Understanding the superconducting pairing mechanism and its connection with other competing states remains unclear. LÄS MER
10. Anion redox processes in novel battery cathode materials investigated by soft X-ray spectroscopy
Sammanfattning : This thesis presents experimental investigations of the electronic structure of emerging and novel cathode materials used in lithium- and sodium-ion batteries. The investigated materials include a range of oxide materials containing the elements nickel and manganese. LÄS MER
