  1. 1. The neutron-induced fission cross section of 233Pa : and the quest for clean and safe nuclear energy

    Författare :Fredrik Tovesson; Andreas Oberstedt; Dietrich Hilscher; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysik; fission; cross section; Pa-233; U-233; fysik; Physics; Fysik; Fysik; Physics;

    Sammanfattning : Neutron-induced fission of 233Pa has been investigated between 1.0 and 8.5 MeV, and the reaction cross section was determined. Due to the short half-life of 233Pa for β-decay, fission events from the daughter product 233U affect the analysis of the protactinium experiment. LÄS MER

  2. 2. Measurements of Neutron-induced Nuclear Reactions for More Precise Standard Cross Sections and Correlated Fission Properties

    Författare :Kaj Jansson; Cecilia Gustavsson; Stephan Pomp; Alexander Prokofiev; Ali Al-Adili; Fanny Farget; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cross Section; Fission; Neutron-induced reactions; Simulation; VERDI; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics;

    Sammanfattning : It is difficult to underestimate the importance of neutron cross section standards in the nuclear data field. Accurate and precise standards are prerequisites for measuring neutron cross sections. Two different projects are presented here with the aim of improving on neutron standards. LÄS MER

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

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

    Sammanfattning : 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.

  4. 4. Fragment Mass Distributions in Neutron-Induced Fission of 232Th and 238U from 10 to 60 MeV

    Författare :Vasily Simutkin; Stephan Pomp; Franz-Josef Hambsch; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ADS; neutron-induced fission; intermediate neutron energies; fragment mass yield; Nuclear physics; Kärnfysik; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics;

    Sammanfattning : Since its discovery, the phenomenon of nuclear fission is the object of extensive theoretical and experimental studies. However, we are still far from a complete understanding of the fission process. LÄS MER

  5. 5. Benchmark of simulation of an ion guide for neutron-induced fission products

    Författare :Zhihao Gao; Andreas Solders; Johan Nyberg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fission products; simulation; Geant4; GEF; MCNPX; neutron flux; gamma spectroscopy;

    Sammanfattning : Independent yield distributions of high-energy neutron-induced fission are of importance to achieve a good understanding of fission. Even though the mass and charge yield distributions of thermal neutron-induced fission are well known, there are few experimental data for high-energy neutron-induced fission. LÄS MER
