  2. 1. Microscopic Properties of Superdeformed Nuclei

    Author : Lennart B Karlsson; Matematisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; statistical physics; gravitation; superdeformation; Nilsson-Strutinsky; modified oscillator potential; moments of inertia; transition energies; rotational bands; quadrupole moments; spin assignments; identical bands; additivity.; Mathematical and general theoretical physics; classical mechanics; relativity; quantum mechanics; kvantmekanik; klassisk mekanik; thermodynamics; Matematisk och allmän teoretisk fysik; termodynamik; relativitet; statistisk fysik; Fysicumarkivet A:1999:Karlsson;

    Abstract : Many high spin rotational bands in superdeformed nuclei have been found in the A ~ 140-150 region, but so far no linking transitions to known normal-deformed states have been found in these nuclei. Therefore, configuration and spin assignments have to be based on indirect spectroscopic information. READ MORE

  4. 2. Necked-in Superdeformed Nuclei

    Author : Lars-Ove Jönsson; Matematisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Matematisk och allmän teoretisk fysik; thermodynamics; statistical physics; gravitation; cranked Nilsson-Strutinsky; superdeformation; necked-in shapes; RPA; giant dipole resonance; finite-range liquid drop model; Mathematical and general theoretical physics; classical mechanics; relativity; quantum mechanics; klassisk mekanik; kvantmekanik; relativitet; statistisk fysik; termodynamik; Fysicumarkivet A:1997:Jönsson;

    Abstract : Superdeformation, i.e. elongated shapes with the longest axis approximately twice as long as the shorter axes, has provided many new insights in nuclear structure. In this dissertation the possibility of forming superdeformed states related to two connected spheres, having a more or less pronounced neck, is investigated. READ MORE

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; statistical physics; gravitation; relativity; Rotational bands; Shell model; Cranked Nilsson-Strutinsky; Pairing interaction; Backbending; Band termination; Proton-neutron pairing; Quadrupole electromagnetic moments and transition strengths; N=Z nuclei; Mathematical and general theoretical physics; quantum mechanics; classical mechanics; klassisk mekanik; Matematisk och allmän teoretisk fysik; thermodynamics; Fysicumarkivet A:2000:Juodagalvis; termodynamik; statistisk fysik; kvantmekanik; relativitet;

    Abstract : One of the goals pursued in the present research was to understand the nuclear phenomena (such as rotational bands, their backbending and termination, deformation, pairing correlations, etc.) using different views provided by different nuclear models. READ MORE

  6. 4. Nuclear Structure and Exotic Decays; Doubly-Magic 56Ni and Semi-Magic 58Ni

    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

  7. 5. 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
