  1. 1. The quest for the neutron tail

    Författare :Thomas Nilsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; radioactivity; measured betadelayed charged particles; neutron detection; beta decay; matter radii; cross-talk; telescope detector; neutron halo;

    Sammanfattning : .... LÄS MER

  3. 2. Search for Gamma-ray Lines from Dark Matter with the Fermi Large Area Telescope

    Författare :Tomi Ylinen; Mark Pearce; Jan Conrad; Staffan Carius; James T. Linnemann; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Fermi; Large Area Telescope; gamma-rays; dark matter; spectral lines; beam test; Physics; Fysik; Astroparticle physics; Astropartikelfysik;

    Sammanfattning : Dark matter (DM) constitutes one of the most intriguing but so far unresolved issues in physics. In many extensions of the Standard Model of particle physics, the existence of a stable Weakly Interacting Massive Particle (WIMP) is predicted. The WIMP is an excellent DM particle candidate.

  4. 3. Excursions Along the Drip Line

    Författare :Thomas Nilsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; beta-decay; cross-talk; exotic nuclei; reaction mechanism; neutron halo; gas-detector telescope; momentum distributions; 8He; neutron detection; radioactivity; 6; dissociation; neutron drip line; 11Be; Borromean systems; 11Li;

    Sammanfattning : The drip lines are the outer boundaries of the chart of the nuclides, terminating the isobaric chains on both sides of the valley of .beta.-stability with respect to stability against particle emission. The neutron drip line is, at the moment, only experimentally accessible for the very lightest elements. LÄS MER

  5. 4. Search for low mass WIMPs with the AMANDA neutrino telescope

    Författare :Anna Davour; Olga Botner; Carlos de los Heros; Mark Pearce; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; dark matter; WIMP; neutrino detection; AMANDA; supersymmetry; Fysik; Physics; Fysik; High Energy Physics; Högenergifysik;

    Sammanfattning : Recent measurements show that dark matter makes up at least one fifth of the total energy density of the Universe. The nature of the dark matter is one of the biggest mysteries in current particle physics and cosmology. LÄS MER

  7. 5. Mesonic fusion - pion and eta meson production in light ion nuclear fusion reactions

    Författare :Irina Zartova; Per-Erik Tegnér; Thomas Nilsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pionic fusion; halo nuclei; cross sections; light mesons; eta-meson; WASA detector; Nuclear physics; Kärnfysik; Nuclear Physics; kärnfysik;

    Sammanfattning : The present thesis describes two experiments performed in the storage ring CELSIUS at The Svedberg Laboratory in Uppsala. In the first experiment the importance of three - nucleon clustering in the six - nucelon system was investigated. The total cross section for the production of the ground state and the 3. LÄS MER
