2. 1. Resonant and Non-Resonant Electron Spectroscopy of Free Molecules and Free Clusters

   Author : Raimund Feifel; Michael Meyer; Uppsala universitet; []
   Keywords : NATURAL SCIENCES; NATURVETENSKAP; Physics; Fysik; Physics; Fysik; fysik; Physics;

   Abstract : Resonant electron spectroscopy has been performed on the diatomic molecules CO, N2 and HCl. Core-excitations were made to bound and dissociative intermediate electronic states. Fundamental interference phenomena are observed and discussed in the framework of ”X-ray Raman Scattering Theory”. READ MORE

4. 2. Multi-Electron Coincidence Studies of Atoms and Molecules

   Author : Egil Andersson; Raimund Feifel; Jan-Erik Rubensson; Kiyoshi Ueda; Uppsala universitet; []
   Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; multi-ionization; electron emission; time-of-flight spectroscopy; coincidence spectroscopy; core-valence ionization; synchrotron radiation; electron correlation; Atomic and molecular physics; Atom- och molekylfysik; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

   Abstract : This thesis concerns multi-ionization coincidence measurements of atoms and small molecules using a magnetic bottle time-of-flight (TOF) spectrometer designed for multi-electron coincidence studies. Also, a time-of-flight mass spectrometer has been used together with the TOF electron  spectrometer for electron-ion coincidence measurements. READ MORE

5. 3. Studies of Single and Multiple Ionization Processes in Rare Gases and some Small Molecules

   Author : Lage Hedin; Raimund Feifel; Dag Hanstorp; Uppsala universitet; []
   Keywords : NATURAL SCIENCES; NATURVETENSKAP; 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

6. 4. Single-photon multiple ionization processes studied by electron coincidence spectroscopy

   Author : Per Linusson; Mats Larsson; Raimund Feifel; Stephen Price; Stockholms universitet; []
   Keywords : NATURAL SCIENCES; NATURVETENSKAP; photoionization; multiple ionization; autoionization; synchrotron radiation; electron coincidence spectroscopy; fysik; Physics;

   Abstract : This thesis is based on studies of multiple ionization of atoms and molecules induced by the absorption of a single photon. For the experimental investigations a time-of-flight magnetic bottle spectrometer has been used to detect the emitted electrons in coincidence. READ MORE

7. 5. Applications of Soft X-Ray Spectroscopy

   Author : Conny Såthe; Jan-Erik Rubensson; Joseph Nordgren; Marcus Agåker; Raimund Feifel; Marc Simon; Uppsala universitet; []
   Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

   Abstract : Soft X-ray emission spectroscopy is an old experimental technique that has seen a strong revival since the advent of new high brilliance soft X-ray sources in the shape of synchrotrons.  This thesis covers a range of applications where soft x-ray techniques have been applied. READ MORE
