  2. 16. Nuclear Structure and Exotic Decays; Doubly-Magic 56Ni and Semi-Magic 58Ni

    Author : Emma Johansson; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Doubly magic; semi magic; 56Ni; 58Ni; high-spin states; fusion-evaporation reactions; cranked Nilsson-Strutinsky calculations; shell-model calculations; prompt proton decay; prompt alpha decay;

    Abstract : The nuclear structure of two nuclei, 56Ni and 58Ni, has been studied using fusion-evaporation reaction experiments. The experiments were performed at the Lawrence Berkeley and Argonne National Laboratories in the U.S.A. READ MORE

  4. 17. Mirror Nuclei - Isospin Symmetry Breaking in the Mass A=35 and A=51 Mirror Nuclei

    Author : Jörgen Ekman; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; high-spin states; shell-model calculations; fusion-evaporation reactions; Nuclear physics; Kärnfysik; Fysicumarkivet A:2004:Ekman; isospin symmetry; Mirror nuclei;

    Abstract : High-spin states in the A=35 mirror nuclei 35Ar and 35Cl and A=51 mirror nuclei 51Fe and 51Mn were populated using fusion-evaporation reactions. The gamma rays were detected in the powerful Ge arrays Gammasphere and GASP, respectively, which operated in conjunction with ancillary detectors for evaporated particles. READ MORE

  5. 18. A Trilogy of Mass A=61 : Superdeformed Structures, Exotic Decay, and Isospin Symmetry

    Author : Lise-Lotte Andersson; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fusion-evaporation reactions; cranked Nilsson-Strutinsky calculations; prompt particle decay; shell-model calculations; mirror nuclei; Fysicumarkivet A:000; high-spin states; Superdeformation;

    Abstract : Three nuclei with mass number A=61 have been studied using four fusion-evaporation experiments carried out at the Oak Ridge, Argonne and Lawrence Berkeley National Laboratories. Normally deformed states in 61Ga were for the first time ever explored and in addition the experimental knowledge of the mirror nucleus 61Zn was extended. READ MORE

  6. 19. Quantum-state Selective Nuclear Decay Spectroscopy

    Author : Ch. Lorenz; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nuclear structure; alpha decay; beta decay; gamma rays; spectroscopy; Penning traps; shell-model calculations; Geant4 Monte Carlo Simulations;

    Abstract : This thesis focusses on the results of two experiments employing Penning traps to prepare pure beams of the 213Ra ground state and 127Cd, which were then studied with the decay-spectroscopy setup TASISpec. The experiments were conducted with SHIPTRAP at the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt, Germany, and JYFLTRAP at the IGISOL Accelerator Facility at the University of Jyväskylä, Finland.

  7. 20. CAD-Model Parsing for Automated Design and Design Evaluation

    Author : Roland Stolt; Staffan Sunnersjö; Ola Isaksson; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Design automation; CAD; KBE; Feature based modelling; Feature recognition; Product development.; Industrial engineering and economy; Industriell teknik och ekonomi;

    Abstract : Product development has both innovative and analytic sides. Starting from the requirements, a design suggestion is generated. In order to assess how well the envisioned design fulfils the requirements, it is sometimes necessary to build a computer model of it for the analysis. READ MORE
