    Keywords : Atomic and molecular physics; Free clusters; Electron spectroscopy; Doped clusters; Laser excitation; Alkali metals; Electronic structure; Geometric structure; X-ray photoelectron spectroscopy XPS ; Resonant Auger spectroscopy RAS ; Near-threshold x-ray absorption fine structure NEXAFS ; Ultraviolet photoelectron spectroscopy UPS ; Detuning; Ultra-fast dissociation UFD ; Sodium; Potassium; Oxygen; Bromomethane; Argon; Xenon; Krypton; Molecular field splitting; Core hole lifetime; Core excitation; Atom- och molekylfysik;

    Abstract : Atoms, molecules and clusters all constitute building blocks of macroscopic matter. Therefore, understanding the electronic and geometrical properties of such systems is the key to understanding the properties of solid state objects. READ MORE

  4. 7. Free Molecular and Metal Clusters Studied by Synchrotron Radiation Based Electron Spectroscopy

    Author : Aldana Rosso; Svante Svensson; Olle Björneholm; Maxim Tchaplyguine; Gunnar Öhrwall; Uwe Hergenhahn; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nanoparticles; free clusters; molecular clusters; metal clusters; photoelectron spectroscopy; synchrotron radiation; local structure; core level spectroscopy; auger spectroscopy; heterogeneous clusters; nucleation; bromomethane; chloromethane; benzene; bromobenzene; chlorobenzene; potassium; sodium; simple metals; Physics; Fysik;

    Abstract : The main purpose of this Thesis is the experimental characterization of the electronic and geometric structures of objects called clusters. A cluster consists of a finite group of bound atoms or molecules. Due to its finite size, it may present completely different properties than those of the isolated atom and the bulk. READ MORE

  5. 8. Multicomponent Clusters/Nanoparticles : An Investigation of Electronic and Geometric Properties by Photoelectron Spectroscopy

    Author : Chaofan Zhang; Olle Björneholm; Maxim Tchaplyguine; Svante Svensson; Gerd Ganteför; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Clusters; Nanoparticles; Alloy; Atmospheric chemistry; Alkali halide; Transition metals; X-ray Photoelectron spectroscopy; Polarizability; Core-shell; Sandwich structure; MAX-lab; BESSY II;

    Abstract : Clusters/nanoparticles are aggregates of a “small” number of building blocks, atoms or molecules, ranging from two up to millions of atoms. Two main groups of clusters have been studied using photoelectron spectroscopy based on synchrotron radiation. READ MORE
