  1. 1. Neutron Halo Nuclei

    Författare :Katarina Wilhelmsen Rolander; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In light nuclei close to the neutron drip-line a spatially extended neutron distribution, the neutron, halo occurs. This is due to the relatively small binding energy of the last neutrons which makes possible quantum mechanical tunnelling of the last neutron(s) far away from the nuclear core. LÄS MER

  3. 2. Study of Halo Nuclei Breakup on Light Targets at Intermediate and High Energies

    Författare :Ioulia Parfenova; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 6He; 15C; cross sections; 8B; longitudinal momentum distributions; D; radioactive beams; halo nucleus; nuclear breakup reactions; 11Be;

    Sammanfattning : The study of exotic nuclei is one of the most important topics in modern nuclear physics. It allows general understanding of the structure and nature of light nuclear systems in the vicinity of the driplines. LÄS MER

  4. 3. Effective Field Theory and One-proton Halo Nuclei

    Författare :EMIL RYBERG; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; radiative capture; halo nuclei; effective field theory; nuclear physics; charge radius;

    Sammanfattning : In this thesis we present formalism for treating one-proton halo nuclei in effective field theory. Halo nuclei are loosely bound systems consisting of a core plus valence nucleon(s). In so called Halo, or Cluster, effective field theory, the core of the halo nucleus is treated as a structureless, effective degree-of-freedom. LÄS MER

  5. 4. Pionic Fusion Study of the 6He Halo

    Författare :Linda Gerén; Christoph Bargholtz; Per-Erik Tegnér; Lennart Isaksson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Sammanfattning : The structure of the halo nucleus 6He has been investigated in a pionic fusion experiment at the CELSIUS storage ring facility in Uppsala. The 4He(d, 6He)π+ reaction was studied 0.6 - 5.0 MeV above threshold in the centre-of-mass frame with a deuteron beam incident on a 4He gas target. LÄS MER

  7. 5. Cluster Effective Field Theory

    Författare :EMIL RYBERG; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; effective field theory; charge radius; resonant state; renormalization; radiative capture; halo nuclei; power counting; nuclear physics; few-body physics;

    Sammanfattning : Halo nuclei are loosely bound systems consisting of a core plus valence nucleon(s). In so called Halo, or Cluster, effective field theory, the core of the halo nucleus is treated as an effective degree-of-freedom without internal structure. LÄS MER
