  2. 1. Laser Photodetachment of Negative Ions - Fundamental Research and Applications

    Author : Pontus Andersson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Negative Ions; Laser Spectroscopy; Photodetachment; Electron Affinity; Mass Spectrometry; Radiative Lifetime; Storage Rings; Mass Spectrometry;

    Abstract : Photodetachment studies of atomic and molecular negative ions in the gas phase are presented. Negative ions are loosely bound quantum systems whose existence is strongly dependent on the correlations between the electrons. READ MORE

  5. 3. 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

  7. 5. A Collinear Angle-Resolved Photoelectron Spectrometer - Instrumental Design and Photodetachment Measurements

    Author : Olle Windelius; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; photoelectron spectrometer; photodetachment; synchrotron radiation; photoionization; Angular distributions;

    Abstract : For more than half a century, photoelectron spectroscopy has been used to investi- gate atoms, ions and molecules. Various techniques have been developed in order to measure electron energies and angular distributions using different radiation sources such as lasers and synchrotrons. READ MORE
