3. 2. Electron - Ion Recombination Studies of Astrophysically Relevant Ions : Storage Ring and Electron Beam Ion Trap Based Measurements

   Författare :Istvan Orban; Reinhold Schuch; Yaming Zou; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; atomic processes; electron-ion recombination; plasma; Physics; Fysik; fysik; Physics;

   Sammanfattning : This thesis contains experimental work that was performed at two state-of-the art devices for electron-ion collision physics, at a heavy-ion storage ring and at an Electron Beam Ion Trap. As a result, absolute recombination rate coefficients for H-like Si, He-like Si, Be-like Si, and Na-like Si, as well as Be-like Ne, Na-like S and Na-like Ar are reported over a wide energy range from μeV to keV.

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

   Författare :Dragan Nikolić; Eva Lindroth; Gleb Gribakin; Stockholms universitet; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

7. 5. Electron-Ion Recombination in Atmospheric and Laboratory Plasmas

   Författare :Anneli Ehlerding; Mats Larsson; Ursel Fantz; Stockholms universitet; []
   Nyckelord :;

   Sammanfattning : In this thesis, the measurements performed at CRYRING, Stockholm University, on the dissociative recombination of C2H+, C2H4+, C2D5+, C3H7+, C3D7+, C4D9+, Na+(D2O), CF+, CF2+ and CO2+ are presented. The dissociative recombination is the reaction in which a positive molecular ion captures an electron and stabilizes the capture by dissociation into neutral fragments. LÄS MER
