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

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

    Sammanfattning : 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. LÄS MER

  3. 2. 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

  4. 3. Three-body systems in the no-core shell model

    Författare :DANIEL SÄÄF; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; core swelling; halo nuclei; no-core shell model; nuclear physics; clusterization;

    Sammanfattning : In this thesis we present the ab initio no-core shell model (NCSM) and we use that framework to study 6He and 6Li computed with a realistic nucleon- nucleon interaction. In particular, we present results for the point-proton radius and the ground-state energy. LÄS MER

  5. 4. Bridging scales in nuclear physics

    Författare :DANIEL SÄÄF; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In this thesis we present the ab initio no-core shell model (NCSM) and use this framework to study light atomic nuclei with realistic nucleon-nucleon interactions. In particular, we present results for radii and ground-state energies of systems with up to twelve nucleons. LÄS MER

  7. 5. Exciting Neutron-rich Nuclei

    Författare :Simon Lindberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; RIKEN; GSI; Unbound States; FAIR; R3B; Radioactive Beams;

    Sammanfattning : Atoms are the building blocks which make up our world. Their stability depends on the atomic nucleus, consisting of protons and neutrons. Nuclei are complex many-body quantum mechanical systems governed by the nucleon-nucleon interaction. LÄS MER
