  2. 1. Excursions Along the Drip Line

    Author : Thomas Nilsson; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. Probing the Drip-Lines through Momentum Distributions

    Author : Martin Smedberg; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 3. Across the drip-line and back: examining 16B

    Author : Ronja Thies; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Analysis; Simulations; FAIR; Unbound Nuclei; GSI; Calibrations; Radioactive Beams; R3B; Neutron-dripline;

    Abstract : Until today, after about one century of research, the atomic nucleus, a basic building block of nature, is still a fascinating puzzle. The field of nuclear physics strives for a better understanding employing both experimental and theoretical efforts. READ MORE

  6. 4. 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

  7. 5. In-Beam Spectroscopy of the Extremely Neutron Deficient Nuclei 169Ir and 110Xe

    Author : Mikael Sandzelius; Bo Cederwall; Lars Westerberg; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; Kärnfysik;

    Abstract : This thesis describes new results obtained from experimental studies of the extremely neutron-deficient isotopes 169Ir and 110Xe, close to the proton drip-line. The experiments use state-of-the-art equipment for nuclear spectroscopy where a large high-resolution Germanium-detector array is coupled to a high-transmission recoil separator and using the highly selective recoil-decay tagging technique.
