  1. 1. Microscopic Properties of Superdeformed Nuclei

    Detta är en avhandling från Mathematical Physics, Lund Institute of Technology, Lund University

    Författare :Lennart B Karlsson; Lunds universitet.; Lund University.; [1999]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  2. 2. Necked-in Superdeformed Nuclei

    Detta är en avhandling från Department of Mathematical Physics, Lund University

    Författare :Lars-Ove Jönsson; Lunds universitet.; Lund University.; [1997]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 3. Comprehensive Gamma-Ray Spectroscopy of 62Zn and Studies of Nilsson Parameters in the Mass A = 60 Region

    Detta är en avhandling från Lund University, Department of Nuclear Physics

    Författare :Jnaneswari Gellanki; Lunds universitet.; Lund University.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; High-spin gamma-ray spectroscopy; superdeformation; 62Zn; Cranked Nilsson-Strutinsky and effective alignments; Fysicumarkivet A:2013:Gellanki;

    Sammanfattning : Popular Abstract in English All ordinary matter around us is made out of atoms. In turn, the building blocks of the atoms are nowadays known to be three types of particles:electrons, protons and neutrons. The latter are called nucleons, as they together form the positively charged nucleus of the atom, around which the electrons are moving. LÄS MER

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

    Detta är en avhandling från Lund University (Media-Tryck)

    Författare :Lise-Lotte Andersson; Lunds universitet.; Lund University.; [2008]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

    Sammanfattning : 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. LÄS MER
