  1. 1. 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

    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

  5. 4. Exploring the Exotic Experimental Investigations far from Stability

    Författare :Karin Markenroth; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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.

  7. 5. 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
