  1. 6. Precise measurements of electron affinities using Laser Photodetachment Threshold Spectroscopy

    Författare :Jose Eduardo Navarro Navarrete; Henning Zettergren; Henning T. Schmidt; Jan-Erik Rubensson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    Sammanfattning :  In this work we have performed Laser Photodetachment Threshold Spectroscopy (LPTS) to determine the electron affinities of the atomic species $^{133}$Cs and $^{16}$O with high precision. The negative ion of Cesium has been produced and investigated at the Gothenburg University Negative Ion and Laser LAboratory (GUNILLA) while the Oxygen anion have been studied in the Double ElectroStatic Ion Ring ExpEriment (DESIREE) at Stockholm University.

  3. 7. Carbon backbone stability of Polycyclic Aromatic Hydrocarbons

    Författare :Michael Wolf; Henning Zettergren; Henrik Cederquist; Henning Schmidt; Stefano Bonetti; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    Sammanfattning : In this thesis I present results from Collision-Induced Dissociation (CID) experiments of Polycyclic Aromatic Hydrocarbons (PAHs) colliding with a stationary target gas at center-of-mass collision energies in the 20–200 eV range. In this energy region nuclear stopping processes dominate, i.e. LÄS MER

  4. 8. Energetic processing of complex molecules in the gas phase

    Författare :Michael Wolf; Henning Zettergren; Henrik Cederquist; T. Henning Schmidt; Christine Joblin; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fysik; Physics;

    Sammanfattning : Collisions between molecules and gas phase targets often lead to various intriguing processes. Such collisions may induce fragmentation of molecules that can be divided into different subsets depending on the projectile, target, and collision energy. LÄS MER

  7. 10. Silurian-Devonian vertebrates from the Northern hemisphere

    Författare :Henning Blom; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; Earth sciences; Geovetenskap; Historical Geology and Paleontology; historisk geologi och paleontologi;

    Sammanfattning : Microscopic remains of early vertebrates such as scales and dermal hone fragments are common in Silurian andDevonian rocks world wide. Although they only represent a small part of the whole animal they still provideimportant information about the organism and its evolution, ecology and distribution. LÄS MER
