  1. 1. Multi-Electron Coincidence Studies of Atoms and Molecules

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Egil Andersson; Uppsala universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; multi-ionization; electron emission; time-of-flight spectroscopy; coincidence spectroscopy; core-valence ionization; synchrotron radiation; electron correlation; NATURAL SCIENCES Physics Atomic and molecular physics; NATURVETENSKAP Fysik Atom- och molekylfysik; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : This thesis concerns multi-ionization coincidence measurements of atoms and small molecules using a magnetic bottle time-of-flight (TOF) spectrometer designed for multi-electron coincidence studies. Also, a time-of-flight mass spectrometer has been used together with the TOF electron  spectrometer for electron-ion coincidence measurements. READ MORE

  2. 2. Theoretical Studies of Magnetism and Electron Correlation in Solids

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Oscar Grånäs; Uppsala universitet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Magnetism; Superconductivity; Electron Correlation; DMFT; DFT; Actinides; multipoles; hidden order; magnetic anisotropy; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : This work presents new development and applications of ab-initio simulation tools for material science. Focus lies on materials with strong electronic correlation and strong spin-orbit coupling. READ MORE

  3. 3. Negative Ions Interacting with Photons and Electrons

    University dissertation from Göteborg : University of Gothenburg

    Author : Anton Lindahl; Göteborgs universitet.; Gothenburg University.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Negative ions; electron correlation; electron affinity; photodetachment; electron collision;

    Abstract : Negative ions are atoms or molecules where an extra electron is bound to neutral system. The nature of negative ions differs fundamentally from neutral and positive systems. The induced dipole potential responsible for the binding of the extra electron supports only a few bound states with relatively small binding energies. READ MORE
