2. 1. Atomic Electrons as Sensitive Probes of Nuclear Properties and Astrophysical Plasma Environments : A Computational Approach

   Author : Asimina Papoulia; Matematisk fysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2021:Papoulia; Computational atomic structure; Relativistic atomic theory; Transition probabilities; Abundance analysis; Landé g­-factors; Hyperfine structure; Nuclear quadrupole moments; Isotope shift; Field shift; Nuclear deformation;

   Abstract : This thesis deals with the relativistic modeling of atoms and ions. To interpret the stellar spectra and gain more insight from astrophysical observations, the underlying processes that generate the spectra need to be well understood and described. READ MORE

4. 2. Isomeric yield ratio measurements with JYFLTRAP : In quest of the angular momentum of the primary fragments

   Author : Vasileios Rakopoulos; Mattias Lantz; Stephan Pomp; Andreas Solders; José Benlliure; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; nuclear fission; angular momentum; fission fragments; isomeric yield ratios; fission products; scission; Penning trap.; Physics with specialization in Nuclear Physics; Fysik med inriktning mot kärnfysik;

   Abstract : In this thesis, isomeric yield ratios of twenty nuclides produced in the fission of natU and 232Th by protons at 25-MeV and natU by high-energy neutrons were studied. The experiments were performed at the IGISOL-JYFLTRAP facility at the University of Jyväskylä. READ MORE

5. 3. Development and Implementation of Methods in Theoretical Chemistry

   Keywords : NATURVETENSKAP; NATURAL SCIENCES; statistical physics; gravitation; relativity; Rotational bands; Shell model; Cranked Nilsson-Strutinsky; Pairing interaction; Backbending; Band termination; Proton-neutron pairing; Quadrupole electromagnetic moments and transition strengths; N=Z nuclei; Mathematical and general theoretical physics; quantum mechanics; classical mechanics; klassisk mekanik; Matematisk och allmän teoretisk fysik; thermodynamics; Fysicumarkivet A:2000:Juodagalvis; termodynamik; statistisk fysik; kvantmekanik; relativitet;

   Abstract : One of the goals pursued in the present research was to understand the nuclear phenomena (such as rotational bands, their backbending and termination, deformation, pairing correlations, etc.) using different views provided by different nuclear models. READ MORE

7. 5. Decay Properties and Hyperfine Interactions in Oriented Alpha-, Beta- and Gamma-emitting Nuclei

   Author : Mats Lindroos; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : The hyperfine interaction has often been described as the bridge between atomic physics and nuclear physics. On the one hand it enables us to study important nuclear phenomena which only manifest themselves in the strong internal fields originating from the surrounding electrons and on the other hand it enables us to study properties of the atomic system or of condensed matter using nuclear probes.
