1. 1. Approaching well-founded comprehensive nuclear data uncertainties : Fitting imperfect models to imperfect data

   Författare :Petter Helgesson; Henrik Sjöstrand; Helmut Leeb; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Evaluated nuclear data; uncertainty propagation; uncertainty quantification; model defects; Gaussian processes; TALYS; TENDL; covariances.; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics;

   Sammanfattning : Nuclear physics has a wide range of applications; e.g., low-carbon energy production, medical treatments, and non-proliferation of nuclear weapons. Nuclear data (ND) constitute necessary input to computations needed within all these applications. LÄS MER

3. 2. Neutron-Induced Light-Ion Production from Iron and Bismuth at 175 MeV

   Författare :Riccardo Bevilacqua; Stephan Pomp; Jan Blomgren; Michael Österlund; Anthony Cowley; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

   Sammanfattning : Radioactive waste management is one of the key issues in sustainability of nuclear energy production. Geological repositories represent today the most appropriate solution to long-term management of high-level radioactive waste. LÄS MER

4. 3. Isomeric yield ratios in nuclear fission

   Författare :Zhihao Gao; Andreas Solders; Ali Al-Adili; Mattias Lantz; Stephan Pomp; Olivier Serot; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear fission; isomeric yield ratio; angular momentum; independent fission yield; ion guide; Applied Nuclear Physics; Tillämpad kärnfysik;

   Sammanfattning : Isomeric yield ratios (IYR), referring to the relative yield of the high spin states of a nucleus to the total yield of all observed states, is an observable of nuclear fission that has the potential to improve our understanding of the fission dynamics. Apart from that, systematic observations of IYRs can also contribute to other areas, such as the validation of fission models, modelling of the r-process in stellar nucleosynthesis, studies of the antineutrino mixing angle, the safety of present-day nuclear reactors, and the design of advanced reactor systems.

5. 4. Neutron induced light-ion production from iron and bismuth at 175 MeV

   Författare :Riccardo Bevilacqua; Stephan Pomp; Magnus Wolke; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; neutron induced reactions; light-ion production; quasi-monoenergetic neutron beam; nuclear data; accelerator driven systems; Nuclear physics; Kärnfysik; Nuclear Physics; kärnfysik; Applied Nuclear Physics; tillämpad kärnfysik;

   Sammanfattning : Light-ions (protons, deuterons, tritons, 3He and α articles) production in the interaction of 175 MeV neutrons with iron and bismuth has been measured using the Medley setup at the The Svedberg Laboratory (TSL) in Uppsala. These measurements have been conducted in the frame of an international collaboration whose aim is to provide the scientific community with new nuclear data of interest for the development of Accelerator Driven Systems, in the range of 20 to 200 MeV.

7. 5. Isomeric yield ratio studies in nuclear reactions and alpha-particle induced fission of Thorium

   Författare :Simone Cannarozzo; Stephan Pomp; Andreas Solders; Stefan Leupold; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Despite decades of research since the initial discovery of nuclear fission, numerous unresolved questions still persist. It is known empirically that fission fragments emerge with high angular momentum. The mechanism responsible for the generation of the large angular momenta observed is one of these open questions.
