2. 21. Mesonic fusion - pion and eta meson production in light ion nuclear fusion reactions

   Author : Irina Zartova; Per-Erik Tegnér; Thomas Nilsson; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; pionic fusion; halo nuclei; cross sections; light mesons; eta-meson; WASA detector; Nuclear physics; Kärnfysik; Nuclear Physics; kärnfysik;

   Abstract : The present thesis describes two experiments performed in the storage ring CELSIUS at The Svedberg Laboratory in Uppsala. In the first experiment the importance of three - nucleon clustering in the six - nucelon system was investigated. The total cross section for the production of the ground state and the 3. READ MORE

4. 22. Simulations And Experiments Of Plasma-Induced Effects In Silicon Detectors

   Author : Ana Maria Gomez L; Ali Al-Adili; Diego Tarrío; Stephan Pomp; Andreas Solders; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; VERDI - VElocity foR Direct particle Identification; PIPS - Passive Implanted Planar Silicon; PDT - Plasma Delay Time; PHD - Pulse Height Defect; FF - Fission Fragment; ToF - Time-of-flight; MCP - Micro Channel Plat; Kärnfysik; Nuclear Physics;

   Abstract : When an atomic nucleus undergoes fission, two fragments with different mass and kinetic energy are emitted. The highly unstable fission fragments (FFs) evaporate prompt neutrons soon after the nucleus splits. READ MORE

5. 23. Neutron Scattering at 96 MeV

   Author : Angelica Öhrn; Jan Blomgren; Robert Haight; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; neutron; elastic scattering; inelastic scattering; differential cross section; optical model potential; Wick s limit; angular distribution; pre-equilibrium; Kärnfysik; Physics; Fysik;

   Abstract : Data on elastic scattering of 96 MeV neutrons from 56Fe, 89Y and 208Pb in the angular interval 10-70° are presented. The previously published data on 208Pb have been extended, as a new method has been developed to obtain additional information at the most forward angles. READ MORE

6. 24. Towards a realistic hyperon reconstruction with PANDA at FAIR

   Author : Adeel Akram; Karin Schönning; Michael Papenbrock; Carl Nettelblad; Marek Jacewicz; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hyperon; Extended Target; Tracking; PANDA; FAIR; Physics with specialization in Nuclear Physics; Fysik med inriktning mot kärnfysik;

   Abstract : The goal of the PANDA (anti-Proton ANnihilation at DArmstadt) experiment at FAIR (Facility for Anti-proton and Ion Research) is to study strong interactions in the confinement domain. In PANDA, a continuous beam of anti-protons () will impinge on a fixed hydrogen (p) target inside the High Energy Storage Ring (HESR), a feature intended to attain high interaction rates for various physics studies e.
