  2. 6. Quantum Nuclear Dynamics in Resonant X-ray Scattering of Gas-Phase and Liquid Systems

    Author : Vinicius Vaz da Cruz; Victor Kimberg; Faris Gel'mukhanov; Hans Ågren; Philippe Wernet; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; resonant inelastic X-ray scattering; X-ray absorption; water; methanol; CO; rotational doppler effect; recoil; wave packet; non-Franck-Condon effect; ultra-fast molecular dissociation; potential energy surface; hydrogen bond; liquid; Teoretisk kemi och biologi; Theoretical Chemistry and Biology;

    Abstract : 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. READ MORE

  4. 7. Soft X-ray Scattering Dynamics Close to Core Ionization Thresholds in Atoms and Molecules

    Author : Johan Söderström; Jan-Erik Rubensson; Lorenzo Avaldi; Uppsala universitet; []
    Keywords : Physics; Soft X-ray emission; Resonant inelastic X-ray scattering; Double excitations; Helium; X-ray-emission-threshold-electron coincidence; Fysik;

    Abstract : 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.

  5. 8. Resonant Inelastic X-ray Scattering of Rare-Earth and Copper Systems

    Author : Kristina Kvashnina; Joseph Nordgren; Clemens Heske; Uppsala universitet; []
    Keywords : Physics; resonant inelastic X-ray scattering; Fysik;

    Abstract : 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. READ MORE
