  1. 1. Collision Induced Fragmentation of Molecules and Molecular Clusters : Knockout Driven Reactions in Fullerenes and PAHs

    Författare :Michael Gatchell; Henning Zettergren; Henrik Cederquist; Henning Schmidt; Ulf Saalmann; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    Sammanfattning : This licentiate thesis covers experimental and theoretical studies of the fragmentation and sub- sequent reactions of fullerenes or Polycyclic Aromatic Hydrocarbons (PAHs). I present results from experiments where atoms or ions collide with fullerenes, PAHs, or clusters of these mole- cules at energies from 100 eV up to tens of keV. LÄS MER

    Sammanfattning : When molecules are excited by photons or energetic particles, they will cool through the emission of photons, electrons, or by fragmenting. Such processes are often thermal as they occur after the excitation energy has been redistributed across all degrees-of-freedom in the system. LÄS MER
