  1. 1. 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. Housing Decay and Maintenance : The Case of Public Housing in Tanzania

    Författare :Felician Komu; Stellan Lundström; Marja Elsinga; KTH; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Landscape architecture; Landskapsarkitektur; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Sammanfattning : The dominant discourse in Tanzania is that home ownership is the most sustainable strategy towards solving housing problem. As a result, housing policy orientation has been towards promotion of home ownership through a land-housing linkage strategy that manifests in improvement of access to identified categories of people usually classified on resources constrained criterion.
