  1. 1. Neutron Halo Nuclei

    Author : Katarina Wilhelmsen Rolander; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : 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. READ MORE

  2. 2. Effective Field Theory and One-proton Halo Nuclei

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

    Abstract : 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. READ MORE

  3. 3. Exploring the Exotic Experimental Investigations far from Stability

    Author : Karin Markenroth; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cross sections; driplines; inbeam spectroscopy; 10; unbound nuclei; 8 B; 11; 17; longitudinal momentum distributions; breakup reactions; projectile fragmentation; resonances; 19 C; elastic resonance scattering; halo nuclei; 13 N;

    Abstract : The exploration of exotic nuclei is one of the most intriguing and fastest expanding fields in modern nuclear physics. In the extreme conditions of unsymmetric neutron-proton distributions and small binding energies many nuclear phenomena not encountered closer to stability have revealed themselves, often as a surprise to the nuclear physics community, the prime example being the development of halo structures as the binding energy diminishes.

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

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

    Abstract : 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. READ MORE

  5. 5. On the Few-Body Character of Light Exotic Nuclei - Analytical Studies of Electromagnetic Processes Involving Loosely Bound Systems

    Author : Christian Forssen; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; few-body physics; exotic nuclei; electromagnetic processes; borromean systems; invariant mass spectra; halo states; nuclear astrophysics;

    Abstract : The few-body character of loosely bound nuclei along the drip lines is studied within an analytical approach. It is argued that the clusterization of these systems leads to a modification of the normal phase space distribution of fragment momenta in breakup reactions. READ MORE
