Those have been investigated as beams, samples or used astargets. Key tools for manipulating spins are external fields with which excitations are possible.To get a better understanding on how this process happens and how to use their final properties,simulations are needed. Those are produced out of theoretical quantum mechanical calculations.Therefore, this thesis deals with the topic of simulating occupation numbers of hyperfine substatesin the presence of external fields. In particular the simulations of already existing devices such asa spin filter or a Sona transition unit are done. As the experimental set-up works with metastable$2S_{1/2}$ hydrogen atoms, the main part of this thesis describes the results for those kind of atoms. Inthe final part, a general description for any kind of hyperfine substates inside the Sona transitionunit is taken. 612 - Cosmic Matter in the Laboratory (POF4-612) G:(DE-HGF)POF4-612 POF4-612 POF IV 0 other External experiment at external facility/ no experiment at GSI (other) EXP:(DE-Ds200)other-20200803 EXP:(DE-Ds200)External_experiment-20200803 EXP:(DE-Ds200)External_experiment-20200803 0 oai:repository.gsi.de:349915 VDB GSI Helmholtzzentrum für Schwerionenforschung GmbH I:(DE-Ds200)20121206GSI GSI 0 P:(DE-Ds200)OR11687 DE-HGF Forschungsbereich Materie Matter and the Universe G:(DE-HGF)POF4-610 G:(DE-HGF)POF4-612 G:(DE-HGF)POF4 G:(DE-HGF)POF4-600 G:(DE-HGF)POF Cosmic Matter in the Laboratory 0 2023 no I:(DE-Ds200)FFN-20210302OR452 FFN FAIR Forschung NRW 0 master VDB I:(DE-Ds200)FFN-20210302OR452 UNRESTRICTED
