  1. 1. 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

  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. 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

  5. 4. Bits and Pieces for the Nuclear Puzzle - Exploring light exotic nuclei with radioactive ion beams

    Författare :Ronja Thies; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ISOLDE; GSI; FAIR; R3B; Neutron-rich nuclei; Radioactive Beams;

    Sammanfattning : Atomic nuclei are a fascinating case of many-body systems governed by quantum behaviour. This fact and the complex nuclear interaction are reasons why there is not yet a complete theory describing all atomic nuclei. Both experimental and theoretical efforts are needed to change this situation. LÄS MER

  7. 5. Probing the Drip-Lines through Momentum Distributions

    Författare :Martin Smedberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; momentum distributions; drip-line; diffraction; 17C; 119C; core shadowing; 6He; neutron stripping; radioactive beams; break-up; intermediate resonance; neutron halo; 8He; 8B; absorption; reaction mechanism;

    Sammanfattning : About a decade ago it was found that nuclei in the vicinity of the neutron drip-line under certain circumstances develop very extended valence neutron distributions, a phenomenon today known as halo states. The recent development of radioactive nuclear beams has provided us with a perfect tool for investigating these particular nuclei. LÄS MER
