  2. 1. MCNPX Simulations for Neutron Cross Section Measurements

    Author : Milan Tesinsky; Janne Wallenius; Alan Tkaczyk; KTH; []
    Keywords : MCNPX; neutron; cross section;

    Abstract : This thesis presents MCNPX simulations of the SCANDAL set-up used at the Theodor Svedberg Laboratory for neutron scattering cross-section measurements. The thesis describes processes and data important for the upcoming off-line data analysis. READ MORE

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

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

    Abstract : 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. READ MORE

  7. 5. Λ-Λ hyperons: the road to estimate the production cross-section in protonproton collisions

    Author : Gandharva Appagere; Maria Doncel Monasterio; Per-Erik Tegnér; Michael Papenbrock; Andreas Heinz; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hyperons; multi-strangeness; neutron-stars; cross-section; Lambda-lambda; Physics; fysik;

    Abstract : In this study, we analyse the $\Lambda$-$\Lambda$ hyperon channel in proton-proton scattering, $pp \mapsto \Lambda\Lambda + K^+K^+, \,\,\Lambda\mapsto p+\pi^-$, with a proton beam energy of $4.5$ GeV using the High Acceptance Di-Electron Spectrometer (HADES) at GSI. READ MORE
