1. Radiative lifetimes of bound excited states in anions : Measurements on long-lived metastable states in atomic anions
Abstract : This thesis presents and discusses the results of measurements of the intrinsic lifetimes of bound excited anionic states. The results are valuable for evaluation of different theoretical models and computation methods and are compared to calculations when available. READ MORE

2. Weak Atomic Interactions
Abstract : An atom or ion can change quantum state, usually through emission or absorption of a photon. The photon has the same energy as the energy difference between the states of the transition. The states, or energy levels, of an atom are quantized and light emitted, or absorbed, from the atom is therefore of specific wavelengths, giving spectral lines. READ MORE

4. Metastable Alumina from Theory: Bulk, Surface, and Growth of κ-Al2O3
Abstract : Aluminas are materials of high technological importance that show a fascinating structural flexibility, with a large amount of different phases (alpha, gamma, eta, delta, kappa, chi, ...) and phase transitions at relatively high temperatures. READ MORE

5. Anomalous Spectral Lines in Space and Laboratory Plasmas - Studies with HST and CRYRING
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
