  4. 2. Spectroscopic study of titanium monohydride and storage ring experiments

    Author : Mathias Danielsson; Ulf Sassenberg; Mats Larsson; Peder Royen; Olli Launila; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TiH; TiD; transition metal hydride; dissociative recombination; Chemical physics; Kemisk fysik; kemisk fysik; Chemical Physics;

    Abstract : This thesis describes two projects, spectroscopy of the astrophysically relevant molecule TiH and its isotopologue TiD, and the dissociative recombination (DR) reaction of astrophysically and atmospherically relevant molecules. Emphasis in the thesis is on the first project. READ MORE

  5. 3. Examination of Dissociative Recombination Processes of Importance for Astrochemically Evolving Interstellar Clouds

    Author : Matthias Hamberg; Wolf Geppert; Peder Royen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dissociative Recombination Astro Chemistry; Chemical physics; Kemisk fysik; kemisk fysik; Chemical Physics;

    Abstract : Each single moment a myriad of processes is taking place throughout the universe. A great deal of them has been found to be dissociative recombination (DR) reactions. In this thesis the major work described are related to experimental determination of reaction rates and how the reaction products splits up into their final fragments. READ MORE

  6. 4. Stark Spectroscopy, Lifetimes and Coherence Effects in Diatomic Molecular Systems

    Author : Annie Hansson; Peder Royen; Michel Herman; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; diatomic; dipole moment; Stark effect; lifetimes; transition moment; coherence effects; EIT; Autler-Townes; Chemical physics; Kemisk fysik;

    Abstract : In this dissertation is exemplified how different laser based methods are applied in high-resolution spectroscopic studies of internal properties of diatomic molecules.A molecular beam apparatus assembly is described, where a laser ablation source is combined with a time-of-flight mass spectrometer.

  7. 5. Experimental Techniques for Studies in Atomic & Molecular Physics

    Author : Filip Heijkenskjöld; Jan-Erik Rubensson; Peder Royen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; spectroscopy; fast ion beam laser spectroscopy; time of flight photoelectron photoelectron coincidence; hyperfine structure; Rabi oscillation; Physics; Fysik;

    Abstract : This thesis is based on a selection of six different experimental techniques used for studies in atomic and molecular physics. The techniques analysed in the thesis are compared to find similarities in strategies and ways to avoid sources of error.Paper 1 deals with collision based spectroscopy with 60 keV Xe6+ ions on sodium and argon gas targets.
