  2. 6. 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

  4. 7. The Nucleus 59Cu - Complex Structure, Shape Evolution, Exotic Decay Modes

    Author : Corina Andreoiu; Fysiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kondenserade materiens egenskaper:elektronstruktur; spectroscopy; relaxation; magnetic resonance; supraconductors; Ge detectors; gamma-ray spectroscopy; charged particle detectors; level scheme; superdeformation; Cranched Nilsson-Strutinsky approach; gamma decay-out mechanism; prompt proton decay; Condensed matter:electronic structure; Kärnfysik; Nuclear physics; magnetic and optical properties; electrical; egenskaper elektriska; magnetiska och optiska ; supraledare; magnetisk resonans; spektroskopi; Fysicumarkivet A:2002:Andreoiu;

    Abstract : High-spin states in the mass A~60 region were populated using the state-of-art gamma-ray spectrometers Gammasphere, Euroball, and GASP in conjunction with dedicated ancillary detectors. In particular, the 59Cu nucleus was studied in several experiments, and a very extensive level scheme was determined. READ MORE

  5. 8. Influence of Nuclear Structure on Decay Properties of Heavy Nuclei

    Author : Daniel Ward; Matematisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; alpha decay; hindrance factors; Skyrme-Hartree-Fock-Bogoliubov model; superheavy nuclei; fission yields; Brownian-shape motion; nuclear structure; nuclear level density; alpha decay; hindrance factors; Skyrme-Hartree-Fock-Bogoliubov model; superheavy nuclei; fission yields; Brownian-shape motion; nuclear structure; nuclear level density; Fysicumarkivet A:2017:Ward;

    Abstract : This dissertation deals with the effects of nuclear structure on the α-decay properties, and on the fission-yielddistributions from the decay of heavy nuclei. The nuclear-structure and decay properties of superheavynuclei is one of the central topics for investigation. READ MORE

  6. 9. Characterization of Different Interface Types for HVDC Extruded Cable Applications

    Author : Espen Doedens; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polymer surfaces; cable peelings; HVDC; Roughness; Charge injection; XLPE; Field enhancement factors; Schottky injection; DC breakdown; Voltage decay; interfaces; Fowler-Nordheim injection; extruded cable; Roughness assisted charge injection.; Charge decay;

    Abstract : In extruded HVDC cable systems a variety of interface types can be found, and the interfacial properties depend on the application within the system. Such applications can be joints, terminations or the cable itself and they will all have different material combinations and manufacturing methods. READ MORE

  7. 10. I väntan på tandvård : Hur tandrötan blev politik

    Author : Christer Lindblom; Bengt Erik Eriksson; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; dentistry; dental profession; historical development; professionialization; dental caries; social problems; politics; tandvård; tandvårdsorganisation; historia; Sverige; 1800-talet; 1900-talet; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : This thesis deals with the political history of dental caries and the evolution of professional dental care in Sweden. For centuries tooth decay was considered an unavoidable nuisance for the individual. During the decades around 1900 dental caries was gradually defmed as a social problem and a preventable national disease. READ MORE
