    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

    Abstract : The subject of the presented work lies in the field of experimental particle physics. The main topic is the study of e+ e− pairs from η meson decays. The data sample used in this work was collected by the WASA-at-COSY collaboration in proton-proton collisions at 1.4 GeV kinetic beam energy. READ MORE
