  2. 1. 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

  5. 3. Effective Charges Near 56Ni and Production of Anti-Nuclei Studied with Heavy-Ion Reactions

    Author : Rickard du Rietz; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; RDDS; Nuclear physics; Kärnfysik; PHENIX; RHIC; mirror nuclei; shell-model calculations; fusion-evaporation reactions; effective charges; anti-deuteron; Heavy-ion reactions; Fysicumarkivet A:000;

    Abstract : This thesis presents the research performed within two different research groups using heavy-ion induced nuclear reactions. They offer the opportunity to investigate different properties of nuclear matter. The results are based on measurements using a variety of different experimental techniques. READ MORE

  6. 4. Observations of rare supernovae and their environments

    Author : Francesco Taddia; Jesper Sollerman; Maryam Modjaz; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Supernova; stellar evolution; metallicity; circumstellar interaction; Astronomy; astronomi;

    Abstract : Supernovae (SNe) are the final stage in the life of massive stars. Their explosion unbinds the progenitor star revealing its inner layers. The SN ejecta interact with the circumstellar material (CSM), providing further information on the progenitor star. READ MORE

  7. 5. PTF12os and iPTF13bvn : Two stripped-envelope supernovae discovered by the Palomar Transient Factory

    Author : Christoffer Fremling; Jesper Sollerman; Ross Church; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sovernovae;

    Abstract : This thesis is based on research made by the intermediate Palomar Transient Factory [(i)PTF], and it is particularly closely tied to the still ongoing research on the stripped-envelope (SE) supernova (SN), iPTF13bvn (Type Ib), that occurred in the nearby galaxy NGC 5806. This SN was initially thought to have been the explosion of a very massive Wolf-Rayet (WR) star, but I have shown that this is very likely not the case. READ MORE
