1. 16. Neutron-Deuteron Scattering and Three-Body Interactions

   Författare :Philippe Mermod; Jan Blomgren; Steven Vigdor; Uppsala universitet; []
   Nyckelord :Nuclear physics; three-body force; neutron; deuteron; elastic scattering; angular distribution; Faddeev equations; Kärnfysik;

   Sammanfattning : High-precision differential cross section data of the neutron-deuteron elastic scattering reaction at 95 MeV are presented. The neutron-proton scattering differential cross section was also measured and used as a reference to allow an accurate absolute normalization of the neutron-deuteron data. LÄS MER

3. 17. Studies of PWO Crystals and Simulations of the p̅p →Λ̅Λ, Λ̅Σ0 Reactions for the PANDA Experiment

   Författare :Sophie Grape; Tord Johansson; Per-Erik Tegnér; Kai-Thomas Brinkmann; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PANDA; antiproton; PWO; hyperon; lambda; simulation; polarisation; spin correlation; Nuclear physics; Kärnfysik; Physics; fysik;

   Sammanfattning : The thesis comprises investigations of two topics related to the PANDA experiment. The first part is dedicated to energy resolution and light yield uniformity studies of PWO crystals for the electromagnetic calorimeter. The second part of the thesis is dedicated to simulation studies of the p̅p→Λ̅Λ and the p̅p→Λ̅Σ0 channels. LÄS MER

4. 18. Experimental Fission Studies at Intermediate Energies

   Författare :Klas Elmgren; Ralf Nolte; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; Kärnfysik; Nuclear physics; Kärnfysik; Applied Nuclear Physics; tillämpad kärnfysik;

   Sammanfattning : A series of nuclear fission experiments have been performed in the intermediate energy range. The dynamics of the fission process have been studied by means of detection of neutrons emitted from compound nuclei formed by ion beams of protons, α-particles, and 12C-ions, all at a beam energy of 100 MeV.

5. 19. Heavy particle interference and diffraction in fast electron transfer collisions

   Författare :Magnus Gudmundsson; Henrik Cederquist; Henning Schmidt; Erik Horsdal; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; fysik; Physics;

   Sammanfattning : This thesis presents experimental results from the synchrotron cooler and storage ring CRYRING on charge transfer processes in fast electron transfer collisions using high-resolution cold target recoil-ion momentum spectroscopy. The main focus of these studies was to investigate a key concept of quantum mechanics: the wave-particle duality. LÄS MER

7. 20. Theoretical studies of chemical dynamics on excited states, driven by non-adiabatic effects : Charge recombination reactions

   Författare :Sifiso Musa Nkambule; Åsa Larson; Adam Kirrander; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mutual neutralization; Dissociative recombination; electronic structure; non-adiabatic; teoretisk fysik; Theoretical Physics;

   Sammanfattning : This thesis is based on theoretical studies of molecular collisions occurring at relatively low to intermediate collision energies. The collisions are called dissociative recombination (DR) and mutual neutralization (MN). LÄS MER
