  2. 2. Investigations on Emission Sources in Proton-Nucleus and Nucleus-Nucleus Collisions

    University dissertation from Department of Physics, Lund University

    Author : Johan Mårtensson; Lunds universitet.; Lund University.; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; High energy interactions; Fysik; Physics; correlation function.; fermion interferometry; t p and d p ratios; target mass dependence; pion angular distribution; pion excitation function; Heavy ion reactions; intermediate energy; cosmic rays; Kosmisk strålning; högenergi;

    Abstract : Emission sources in proton-nucleus and nucleus-nucleus collisions at intermediate energies have been studied. Pion excitation functions from the absolute threshold to 500 MeV have been measured with an ion beam of continuously varying energy with an energy resolution of 1 MeV. READ MORE

  3. 3. Carbon backbone stability of Polycyclic Aromatic Hydrocarbons

    University dissertation from Stockholm University

    Author : Michael Wolf; Stockholms universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    Abstract : 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. READ MORE

  4. 4. Electronic excitation, luminescence and particle emission : Studying ion-induced phenomena in ToF-MEIS

    University dissertation from Uppsala : Uppsala University

    Author : Svenja Lohmann; Uppsala universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TOF-MEIS; ion beam analysis; deep UV; desorption; electronic sputtering; TiN;

    Abstract : Medium energy ion scattering (MEIS) is an experimental technique for the high-resolution depth profiling of thin films. Commonly, ions with energies between several ten to a few hundred keV are employed as probes, and backscattered particles are detected. READ MORE

  5. 5. Statistical Feature Selection With Applications in Life Science

    University dissertation from Institutionen för fysik, kemi och biologi

    Author : Roland Nilsson; Linköpings universitet.; Linköpings universitet.; [2007]
