  1. 1. Dynamics in the Dissociative Recombination of Small Polyatomic Molecular Ions

    Författare :Vitali Zhaunerchyk; Richard Thomas; Xavier Urbain; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dissociative recombination; Molecular physics; Molekylfysik; Physics; fysik;

    Sammanfattning : Dissociative recombination (DR) is a process in which a positive molecular ion recombines with an electron and subsequently dissociates into neutral fragments. Among the different types of molecular ion-electron reactions DR deserves particular attention due to the important role it plays in low-temperature and low-density plasmas. LÄS MER

  3. 2. Interactions of chiral ions and molecules in gas phase : Towards an understanding of chiral recognition mechanism

    Författare :Oleksii Rebrov; Mats Larsson; Richard Thomas; Vitali Zhaunerchyk; Anne Zehnacker-Rentien; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fysik; Physics;

    Sammanfattning : This thesis comprises the research related to interactions of enantiopure amino acids with chiral and achiral molecules in gas phase. The investigation of the mechanism responsible for chiral discrimination is of the special interest in this work. LÄS MER

  4. 3. Single-photon multiple ionisation of atoms and molecules investigated by coincidence spectroscopy : Site-specific effects in acetaldehyde and carbon dioxide

    Författare :Sergey Zagorodskikh; Raimund Feifel; Vitali Zhaunerchyk; Melanie Mucke; Maria Novella Piancastelli; Tom Field; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; acetaldehyde; carbon dioxide; xenon; electron correlation; double ionisation; triple ionisation; core-valence ionisation; site-specific Auger decay; multiple Auger decay; branching ratios; site-specific photodissociation; molecular rearrangement; time-of-flight multi-electron-ion coincidence spectroscopy; synchrotron radiation; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Sammanfattning : In this thesis, multiple ionisation processes of free atoms and molecules upon single photon absorption are studied by means of a versatile multi-electron-ion coincidence spectroscopy method based on a magnetic bottle, primarily in combination with synchrotron radiation. The latter offered the possibility to access not only valence but also core levels, revealing processes, which promote the target systems into different charge states. LÄS MER
