  1. 1. Development of Experimental Methods, Data Analysis and Standards in Atomic Spectroscopy

    Author : Kasper Öberg; Astronomi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Atom- och molekylärfysik; Atomic and molecular physics; ytterbium; spectroscopy; radiative lifetimes; oscillator strengths; neon; line shapes; light sources; Fourier-transform spectroscopy; branching fractions; Stark effect; spectroscopic techniques; LIF; Atomic data;

    Abstract : The focus of this work is on the experimental techniques and data analysis in atomic spectroscopy. Improved methods for the analysis of spectra and the determination of level energies are presented. Most of these are based on a rigorous statistical treatment of the spectroscopic data. READ MORE

  2. 2. Computed Tomography of Acetabular Cup Wear and Effect of Surface Roughness on Wear and Oxidation of UHMWPE Hip Prostheses

    Author : Anneli Jedenmalm; Ulf Gedde; André Stark; Karin Jacobson; Nicklas Axén; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hip prostheses; Computed Tomography; Surface roughness; UHMWPE; Wear; Coating; Gamma-irradiation; pin-on-disc; hip simulator; Medical engineering; Medicinsk teknik;

    Abstract : Aseptic loosening is the most common complication in total hip replacement (5- 10% at 10 years follow up). The magnitude of the problem is illustrated by the fact that about one million hip prostheses are implanted worldwide each year. READ MORE

  3. 3. Quantum-state Selective Nuclear Decay Spectroscopy

    Author : Ch. Lorenz; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nuclear structure; alpha decay; beta decay; gamma rays; spectroscopy; Penning traps; shell-model calculations; Geant4 Monte Carlo Simulations;

    Abstract : This thesis focusses on the results of two experiments employing Penning traps to prepare pure beams of the 213Ra ground state and 127Cd, which were then studied with the decay-spectroscopy setup TASISpec. The experiments were conducted with SHIPTRAP at the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt, Germany, and JYFLTRAP at the IGISOL Accelerator Facility at the University of Jyväskylä, Finland.
