    Keywords : NATURVETENSKAP; NATURAL SCIENCES; statistical physics; gravitation; relativity; Rotational bands; Shell model; Cranked Nilsson-Strutinsky; Pairing interaction; Backbending; Band termination; Proton-neutron pairing; Quadrupole electromagnetic moments and transition strengths; N=Z nuclei; Mathematical and general theoretical physics; quantum mechanics; classical mechanics; klassisk mekanik; Matematisk och allmän teoretisk fysik; thermodynamics; Fysicumarkivet A:2000:Juodagalvis; termodynamik; statistisk fysik; kvantmekanik; relativitet;

    Abstract : One of the goals pursued in the present research was to understand the nuclear phenomena (such as rotational bands, their backbending and termination, deformation, pairing correlations, etc.) using different views provided by different nuclear models. READ MORE

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

    Author : DANIEL SÄÄF; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; core swelling; halo nuclei; no-core shell model; nuclear physics; clusterization;

    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. 3. Multistep Shell Model in the Complex Energy Plane

    Author : Zhenxiang Xu; Ramon Wyss; Chong Qi; Marek Płoszajczak; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this thesis the properties of unbound nuclei like 12,13Li are studiedby extending the multistep shell model to the complex energy plane. Thenuclei 12Li and 13Li are described starting from the one-particle states in 10Liand two-particle states in 11Li. The ground state of 12Li is found to be anantibound state. READ MORE

  6. 4. Ghost in the shell : Studies on subsurface oxygen in oxide-derived copper nanocube catalysts

    Author : Liu Chang; Lars Pettersson; Anders Nilsson; Tore Brinck; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

    Abstract : With the passage of time and the advancement of our industrial civilization, environmental concerns have become more and more recognized since the 1990s. Carbon dioxide reduction reactions are capable of converting carbon dioxide into valuable hydrocarbons and reducing the carbon emission from the combustion of fossil fuels. READ MORE

  7. 5. A Waterborne Colloidal Model System Consisting of Fluorinated Spheres Bearing Grafted PEG: Synthesis, Characterization and Properties

    Author : Jeanette Ulama; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; colloidal model system; steric stabilization; core-shell; poly ethylene glycol PEG ; heptafluorobutyl methactylate HFBMA ; fluorinated; polymer; phase behavior; short-range attractions; semi-batch emulsion polymerization; small angle X-ray scattering SAXS ; smearing effects; dynamic light scattering DLS ; cryogenic-transmission electron microscopy cryo-TEM ;

    Abstract : Model systems have expanded our knowledge of numerous phenomena in Colloid Science, such as the appearance of glasses, order-disorder transitions involving crystals and attraction induced formation of gels. So far, the existing colloidal model systems have been limited mainly to nonaqueous media. READ MORE
