    Author : Sergey Zagorodskikh; Uppsala universitet.; [2016]
    Keywords : 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;

    Abstract : 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. READ MORE

    Abstract : Ljus kan användas till många saker, allt från att sända radiosignaler och skicka information i optiska fibrer, till att lysa upp hem och utvinna energi via solceller. Det ljus vi är mest vana vid som människor är ett intervall av våglängder mellan 400 och 700 nanometer (en nanometer är en miljarddels meter), som svarar mot alla synliga färger mellan rött och violett.
