  2. 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

    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

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

    Författare :Lise-Lotte Andersson; Kärnfysik; []
    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

  5. 5. Studies of collective phenomena in neutron deficient nuclei : by means of lifetime measurements, angular correlation measurements and the recoil-decay tagging technique

    Författare :Karin Andgren; Bo Cederwall; Paul Nolan; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; heavy-ion reactions; multi-detector arrays; recoil separator; in-beam gamma-ray spectroscopy; high spin states; lifetime measurements; recoil-decay tagging; nuclear shape; Nuclear physics; Kärnfysik;

    Sammanfattning : The nucleus is a mesoscopic system that retains features from both the quantum and macroscopic worlds. A basic property of a macroscopic body is its shape. Nuclear shapes can be deduced from experimental data as they influence the excitation mode of the nucleus and hence the energies and lifetimes of its excited levels. LÄS MER
