  2. 26. Studies of Single and Multiple Ionization Processes in Rare Gases and some Small Molecules

    Author : Lage Hedin; Raimund Feifel; Dag Hanstorp; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik; Physics with spec. in Atomic; Molecular and Condensed Matter Physics;

    Abstract : In this thesis various aspects of photoionization are investigated with respect to both single and multiple electron emission from atoms and molecules. The studies include both valence and core levels and involve transitions which leave the atoms or molecules in various charge states. READ MORE

  4. 27. Investigations of some diatomic molecules : the hydrides of selenium, antimony and silicon and the platinum oxide

    Author : Ulf Sassenberg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis is an extension and a summary of investigations on the electronic spectra of gaseous SeH/D, SbH/D, PtO and to some minor extent also of gaseous SiH. Rotational analyses are performed on each molecule.SeH/D molecules were generated in photolysis reactions using 12 µs long light flashes. READ MORE

  5. 28. Double Inner-Shell Vacancies in Molecules

    Author : Dimitris Koulentianos; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Molecular electronic states possessing a double core-vacancy, referred to as double-core-hole (DCH) states, were predicted more than thirty years ago, to have interesting properties, which would allow one to probe matter in a much more detailed way compared to conventional single core-vacancy techniques. Though DCH states are characterized by low cross-sections compared to the dominant single-core-hole (SCH) states, which implies experimental challenges, the development of third generation synchrotron radiation (SR) facilities and X-ray free electron lasers (XFEL), in combination with advanced spectroscopy techniques, resulted recently in a significant number of scientific works reporting on the observation of different types of DCH states.

  6. 29. Photon induced fluorescence studies of molecules using synchrotron radiation

    Author : Jesús Álvarez Ruiz; KTH; []
    Keywords : Fluorescence; synchrotron radiation; superexcited states; UV.;

    Abstract : This Licentiate thesis presents research accomplished at theSection of Atomic and Molecular Physics at the Royal Instituteof Technology in Stockholm using photon induced fluorescencespectroscopy (PIFS) during the last two years.The main results presented are summarized:- Neutral photodissociation in CO was observed aftersynchrotron photon excitation in the range 19-26 eV bycollecting dispersed fluorescence from excited neutral C atoms.
