    Abstract : Eta Carinae is one of the most massive and luminous stars in the Galaxy. A huge bipolar nebula and an equatorial disk give the object a characteristic shape. Close to the star there are gas clouds, which emit intriguing emission line spectra. READ MORE

  4. 17. The Nucleus 59Cu - Complex Structure, Shape Evolution, Exotic Decay Modes

    Author : Corina Andreoiu; Fysiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kondenserade materiens egenskaper:elektronstruktur; spectroscopy; relaxation; magnetic resonance; supraconductors; Ge detectors; gamma-ray spectroscopy; charged particle detectors; level scheme; superdeformation; Cranched Nilsson-Strutinsky approach; gamma decay-out mechanism; prompt proton decay; Condensed matter:electronic structure; Kärnfysik; Nuclear physics; magnetic and optical properties; electrical; egenskaper elektriska; magnetiska och optiska ; supraledare; magnetisk resonans; spektroskopi; Fysicumarkivet A:2002:Andreoiu;

    Abstract : High-spin states in the mass A~60 region were populated using the state-of-art gamma-ray spectrometers Gammasphere, Euroball, and GASP in conjunction with dedicated ancillary detectors. In particular, the 59Cu nucleus was studied in several experiments, and a very extensive level scheme was determined. READ MORE

  5. 18. Dynamics of Photoinduced Processes in Dye-Sensitized Nanocrystalline Semiconductor Films--Reactions in the Photoactive Part of the Grätzel Solar Cell

    Author : Gabor Benko; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; supraledare; magnetisk resonans; spektroskopi; magnetiska och optiska ; egenskaper elektriska; Kondenserade materiens egenskaper:elektronstruktur; spectroscopy; relaxation; magnetic resonance; supraconductors; Kemi; Condensed matter:electronic structure; electrical; femtosecond spectroscopy; solar cells; Chemistry; excited states; photoinduced electron transfer; transition metal complexes; nanocrystalline titanium dioxide; dye sensitization; porous semiconductor film; magnetic and optical properties;

    Abstract : The key materials used to convert solar energy into electricity in the Grätzel-type solar cells are dye molecules and titanium dioxide particles attached to each other. The former are similar to those in common products like purple pigments in blueberry juice, while the latter are like sunscreen, white paint, or toothpaste. READ MORE

    Abstract : The present thesis is concerned with the theoretical study of x-ray photoemission spectra from clean and adsorbate-covered metal surfaces. The main tool is ab initio density functional (DFT) total energy calculations. READ MORE

  7. 20. Static and Dynamic Correlation Effects in Atoms

    Author : Nils-Erik Dahlen; Matematisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; magnetic and optical properties; electrical; Condensed matter:electronic structure; relaxation; magnetic resonance; supraconductors; spectroscopy; Kondenserade materiens egenskaper:elektronstruktur; Atom- och molekylärfysik; Atomic and molecular physics; spektroskopi; magnetisk resonans; egenskaper elektriska; supraledare; magnetiska och optiska ; variational energies; double ionization; Electron correlation; laser-atom interaction; Fysicumarkivet A:2002:Dahlen; conserving approximations; Green s functions; GW-approximation;

    Abstract : The thesis considers the effects of electron correlation by studying the two opposite limits of atoms in the ground state and atoms in strong laser pulses. Computational methods and theoretical approaches differ significantly due to the different physical processes that are studied in these two cases. READ MORE
