  1. 1. Mechanistic Studies of Organocopper Chemistry by NMR Spectroscopy: Conjugate Additions to Alkynes and Alkenes

    University dissertation from Chalmers University of Technology

    Author : Karolina Nilsson; Chalmers tekniska högskola.; Chalmers University of Technology.; [1997]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry; mechanism; conjugate addition; organocopper reagents; ynoates; ynones; enoates; pi-complexes; lithium dimethylcuprate; cyanocuprate; 13C and 15N NMR spectroscopy; 6Li; 1H-HOESY;

    Abstract : This thesis focuses on the mechanisms of organocopper reactions, in particular the reactions with activated alkynes (ynoates and ynones). These reactions are of interest in the formation of new highly functionalized double bonds with control of the stereochemistry. READ MORE

  2. 2. Chiral Lithium N,P-amide Complexes. Synthesis, Applications and Structural Studies by NMR and DFT

    University dissertation from Chalmers University of Technology

    Author : Petra Rönnholm; Göteborgs universitet.; Gothenburg University.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 6Li NMR; Asymmetric synthesis; N; P-ligands; DFT; Molecular mechanics;

    Abstract : Enantiospecific synthesis reactions are of intense interest, owing to the increasing request for enantiopure compounds in both research and industry. Lithium amides containing a secondary chelating group are a class of powerful ligands for asymmetric addition reactions. READ MORE

  3. 3. Improving the Neutron Cross-section Standards 238U(n,f) and 6Li(n,a) Measurements and Simulations

    University dissertation from Polacksbackens repro

    Author : Kaj Jansson; Uppsala universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics;

    Abstract : Improving or extending the range of cross-section standards, which in general are believed to be well known, require good control of the experimental conditions and the uncertainties involved. Two experiments that aspire to improve two different neutron cross-section standards, 238U(n,f) and 6Li(n,a, are presented in this thesis. READ MORE

  4. 4. Three-body systems in the no-core shell model

    University dissertation from Chalmers University of Technology

    Author : Daniel Sääf; Chalmers tekniska högskola.; Chalmers University of Technology.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; no-core shell model; nuclear physics; halo nuclei; clusterization; core swelling;

    Abstract : In this thesis we present the ab initio no-core shell model (NCSM) and we use that framework to study 6He and 6Li computed with a realistic nucleon- nucleon interaction. In particular, we present results for the point-proton radius and the ground-state energy. READ MORE

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

    University dissertation from Stockholm : Department of Physics, Stockholm University

    Author : Irina Zartova; Stockholms universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; pionic fusion; halo nuclei; cross sections; light mesons; eta-meson; WASA detector; NATURAL SCIENCES Physics Nuclear physics; NATURVETENSKAP Fysik 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
