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

    Författare :Aldana Rosso; Svante Svensson; Olle Björneholm; Maxim Tchaplyguine; Gunnar Öhrwall; Uwe Hergenhahn; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
