    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

    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

  6. 4. Studies of Dielectric Relaxation in Solid Polymers and Composites

    Author : Mohsen Safari Ardi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dielectric permittivity; time-domain dielectric relaxation; composite; carbon black; poly vinylidene fluoride ; interfacial polarization; poly vinyl chloride ; coated carbon fibre; epoxy; poly methyl methacrylate ; nitrile butadiene rubber; ethylene-vinyl acetate copolymer; polyamide 6;

    Abstract : Non-linear characteristics of homogeneous solid polymers and solid polymer-based composites have been studied both experimentally and theoretically. In particular experimental studies of non-linear dielectric response of six homogeneous solid polymeric materials and the influence of the composition on the properties of solid polymer-based composites with high dielectric permittivities have been carried out and a theoretical study of dipole-dipole interaction in solids based on a formulation due to P.
