  2. 1. Excited States in Negative Ions

    Author : Johan Rohlén; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Negative Ions; Photodetachment; Atomic Physics; Experimental Physics;

    Abstract : This thesis covers experimental studies of atomic negative ions with the main goal of increasing our fundamental understanding of these fragile quantum systems. Comparisons of measurements and calculations have been used to increase our understanding of these highly correlated, yet simple, systems. READ MORE

  6. 4. Autoionizing states and their relevance in electron-ion recombination

    Author : Dragan Nikolić; Eva Lindroth; Gleb Gribakin; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electron-ion recombination; Autoionization; Electron correlation calculations; Doubly excited states; Relativistic many-body perturbation theory; Coupled-cluster methodology; Intruder state problem; Physics; Fysik;

    Abstract : Atomic physics plays an important role in determining the evolution stages in a wide range of laboratory and cosmic plasmas. Therefore, the main contribution to our ability to model, infer and control plasma sources is the knowledge of underlying atomic processes. READ MORE

  7. 5. Photodetachment of Negative Ions. Experimental Investigations of Threshold and Continuum Structures

    Author : Joakim Sandström; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; electron correlation; resonance ionization spectroscopy; doubly excited states; electron affinity; accelerator mass spectrometry; photodetachment;

    Abstract : In this thesis photodetachment studies of atomic negative ions where one or several electrons are detached from a negative ion are presented. Negative ions are unique objects since their formation and destruction mechanisms strongly depend on the correlated motion of the valence electrons. READ MORE
