  2. 1. Investigations of Reaction Cross Sections for Protons and 3He

    Author : Mattias Lantz; Anders Ingemarsson; Livius Trache; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; reaction cross section; protons; 3He; experimental method; transmission method; optical model; parametrization; matter distributions; Kärnfysik; Nuclear physics; Kärnfysik;

    Abstract : The reaction cross section gives the probability that a particle will undergo a nonelastic process when passing through a nuclear medium. Therefore reaction cross section data are of importance both for theoretical studies and for applications in such diverse fields as medicine, biology, astrophysics and accelerator-driven transmutation of nuclear waste.

  4. 2. Isomeric yield ratios in nuclear fission

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

    Abstract : 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. 3. Collectivity in Neutron-Rich Erbium Isotopes

    Author : Aila Gengelbach; Johan Nyberg; Lantz Mattias; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear structure; collective excitations; rare-earth nuclei; gamma-ray spectroscopy; AGATA; PRISMA; Physics with specialization in Nuclear Physics; Fysik med inriktning mot kärnfysik;

    Abstract : Neutron-rich rare-earth nuclei around the maximum of collectivity are predicted to exist with an extremely stable intrinsic configuration in their ground-state structure. Due to the high degree of axial symmetry and large deformation, these nuclei are also excellent candidates for having long-lived high-K isomers. READ MORE

  7. 5. Studying neutron-induced fission at IGISOL-4 : From neutron source to yield measurements and model comparisons

    Author : Andrea Mattera; Stephan Pomp; Mattias Lantz; Andreas Solders; Jonathan Wilson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Fission yields represent the probability of producing a certain nuclide in a fission event, and are important observables for fission research. For applications, accurate knowledge of the yields is fundamental at all stages of the fuel cycle of nuclear reactors, e.g., for reactivity calculations, or to estimate (spent) fuel inventory.
