1. On the Challenges for Time-of-Flight Electron Spectroscopy at Storage Rings
Sammanfattning : Time-of-flight (TOF) techniques for energy analysis have been common in electron spectroscopy for many decades. TOF-based electron spectrometers benefit from higher transmission and information rate compared to their main competitor: the hemispherical analyser; the drawback being their lower energy resolution.

2. Multi-Electron Coincidence Studies of Atoms and Molecules
Sammanfattning : 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. LÄS MER
3. Photoelectron Spectroscopy on HCl and DCl : Synchrotron Radiation Based Studies of Dissociation Dynamics
Sammanfattning : Dissociation dynamics of the ionized molecules HCl and the deuterated system DCl has been studied in gas-phase using synchrotron based photoelectron spectroscopy (PES).The inner-valence "(4σ)-1" photoionization band for DCl and HCl was recorded using maximum resolution in order to probe an interference pattern between a dissociative and a bound electronic state.

4. Experimental Techniques for Studies in Atomic & Molecular Physics
Sammanfattning : 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.

5. Multi-Electron and Multi-Ion Coincidence Spectroscopy of Single-Photon Ionization Processes in Molecules
Sammanfattning : This thesis presents experimental investigations of multi-electron and multi-electron-multi-ion coincidence measurements of samples in the gas phase utilizing a versatile time-of-flight magnetic bottle spectrometer technique. These investigations of multiply ionized atomic and molecular species provide valuable information on, and understanding of, ionization processes and dissociation mechanisms highly relevant to the development of electronic structure theories.
