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. Gamow -Teller Beta Decay in Drip Line Nuclei

   Author : Fredrik Frisk; Matematisk fysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; gravitation; relativity; proton drip line; Gamow-Teller giant resonance; beta decay; Hartree-Fock calculation; prolate; oblate; deformed nuclei; Tamm-Dancoff approximation; Mathematical and general theoretical physics; quantum mechanics; classical mechanics; statistical physics; thermodynamics; Matematisk och allmän teoretisk fysik; klassisk mekanik; kvantmekanik; relativitet; statistisk fysik; termodynamik; Fysicumarkivet A:1997:Frisk;

   Abstract : Before radioactive ion beams became available, the Gamow-Teller (GT) giant resonance was studied using charge-exchange reactions such as (p,n) and (He,t). In beta-stable nuclei, which can be used as targets, the GT giant resonance lies above the ground state of the mother nucleus. 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. 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

7. 5. Structure of Deformed Proton-rich Nuclei Studied by Beta-decay

   Author : Petter Urkedal; Matematisk fysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematical and general theoretical physics; classical mechanics; relativity; quantum mechanics; termodynamik; statistisk fysik; relativitet; kvantmekanik; klassisk mekanik; Matematisk och allmän teoretisk fysik; thermodynamics; gravitation; statistical physics; Physics; nuclear-structure beta-decay proton-rich drip-line neutrino; Fysik; Fysicumarkivet A:2002:Urkedal;

   Abstract : Nuclear structure is studied using beta-decay reactions as a probe and focusing on medium-heavy proton-rich nuclei. One of the included articles is a systematic study covering a major part of the nuclear chart, especially searching for nuclei which may be sensitive to sub-MeV neutrinos... READ MORE
