  1. 1. On Alpha-decay and Alpha Clustering

    Författare :Gordana Dodig Crnkovic; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The half-life for the Alpha-decay of 212 Po is calculated within a harmonic oscillator representation. Clustering induced by the nuclear interaction appear by considering alarge configuration space. The role of clusterisation in the alpha-decay process isclearly demonstrated. LÄS MER

  3. 2. Quantum-state Selective Nuclear Decay Spectroscopy

    Författare :Ch. Lorenz; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nuclear structure; alpha decay; beta decay; gamma rays; spectroscopy; Penning traps; shell-model calculations; Geant4 Monte Carlo Simulations;

    Sammanfattning : This thesis focusses on the results of two experiments employing Penning traps to prepare pure beams of the 213Ra ground state and 127Cd, which were then studied with the decay-spectroscopy setup TASISpec. The experiments were conducted with SHIPTRAP at the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt, Germany, and JYFLTRAP at the IGISOL Accelerator Facility at the University of Jyväskylä, Finland.

  4. 3. Spectroscopy along Decay Chains of Element 114, Flerovium

    Författare :Anton Såmark-Roth; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Superheavy elements; Flerovium; Nuclear Structure; Spectroscopy; Alpha decay; Electromagnetic decay; Spontaneous fission; Germanium detectors; Fysicumarkivet A:2021:Såmark-Roth;

    Sammanfattning : This thesis focusses on a nuclear spectroscopy experiment conducted to study α-decay chains stemming from isotopes of flerovium (element Z = 114). An upgraded TASISpec decay station was placed behind the gas-filled separator TASCA at the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt, Germany. LÄS MER

  5. 4. Influence of Nuclear Structure on Decay Properties of Heavy Nuclei

    Författare :Daniel Ward; Matematisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; alpha decay; hindrance factors; Skyrme-Hartree-Fock-Bogoliubov model; superheavy nuclei; fission yields; Brownian-shape motion; nuclear structure; nuclear level density; alpha decay; hindrance factors; Skyrme-Hartree-Fock-Bogoliubov model; superheavy nuclei; fission yields; Brownian-shape motion; nuclear structure; nuclear level density; Fysicumarkivet A:2017:Ward;

    Sammanfattning : This dissertation deals with the effects of nuclear structure on the α-decay properties, and on the fission-yielddistributions from the decay of heavy nuclei. The nuclear-structure and decay properties of superheavynuclei is one of the central topics for investigation. LÄS MER
