  3. 2. Mirror Nuclei - Isospin Symmetry Breaking in the Mass A=35 and A=51 Mirror Nuclei

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

    Sammanfattning : 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. LÄS MER

  4. 3. Exciting Neutron-rich Nuclei

    Författare :Simon Lindberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; RIKEN; GSI; Unbound States; FAIR; R3B; Radioactive Beams;

    Sammanfattning : Atoms are the building blocks which make up our world. Their stability depends on the atomic nucleus, consisting of protons and neutrons. Nuclei are complex many-body quantum mechanical systems governed by the nucleon-nucleon interaction. LÄS MER

  5. 4. Necked-in Superdeformed Nuclei

    Författare :Lars-Ove Jönsson; Matematisk fysik; []
    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

  7. 5. On the Few-Body Character of Light Exotic Nuclei - Analytical Studies of Electromagnetic Processes Involving Loosely Bound Systems

    Författare :Christian Forssen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; few-body physics; exotic nuclei; electromagnetic processes; borromean systems; invariant mass spectra; halo states; nuclear astrophysics;

    Sammanfattning : The few-body character of loosely bound nuclei along the drip lines is studied within an analytical approach. It is argued that the clusterization of these systems leads to a modification of the normal phase space distribution of fragment momenta in breakup reactions. LÄS MER
