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

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

   Abstract : 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. READ MORE

   Keywords : 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;

   Abstract : 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. READ MORE

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

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

   Abstract : 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. READ MORE
