  2. 2. Laboratory studies of forbidden decay processes in stored ions

    Author : Jonas Gurell; Sven Mannervik; Ahmed Al-Khalili; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Atomic physics; Atomfysik; fysik; Physics;

    Abstract : Measurements of atomic and ionic data has been an active research area since the beginning of spectroscopic studies. The experimental data deduced from thesestudies are of great interest for our understanding of fundamental as well as applied physics. READ MORE

  3. 3. Experimental Studies of Neutron Emission Induced by Heavy-Ion Scattering

    Author : Pawel Nadel-Turonski; Leif Nilsson; Adriaan van den Berg; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; neutron; inelastic scattering; heavy ions; position sensitive silicon detectors; storage ring; cluster-jet target; differential cross section; Kärnfysik; Nuclear physics; Kärnfysik;

    Abstract : A beam of 250A MeV 17O ions was scattered from argon and xenon targets. The large excess of fast neutrons compared with statistical model calculations that was observed earlier for xenon, was confirmed and found for argon as well. READ MORE

  4. 4. Electron - Ion Recombination Data for Plasma Applications : Results from Electron Beam Ion Trap and Ion Storage Ring

    Abstract : This thesis contains results of electron-ion recombination processes in atomic ions relevant for plasma applications. The measurements were performed at the Stockholm Refrigerated Electron Beam Ion Trap (R-EBIT) and at the CRYRING heavy-ion storage ring. READ MORE

  5. 5. Atomic Spectroscopy for Applications in Energy Technology

    Author : Thomas Lennartsson; Astronomi - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; atomic structure; plasma diagnostics; branching fractions; gas discharges; highly charged ions; extreme ultraviolet spectra; time-resolved spectroscopy;

    Abstract : This thesis intends to provide spectroscopic information which may be of use in the investigation of low-density plasmas. Developed since the 19th century, the spectroscopic approach has proven to be a versatile method for measuring properties in hot gases, such as electron and ion temperatures and densities, the abundance of various elements in the gas, etc. READ MORE
