Abstract: Since the beginning of the early quantum mechanics, devices have been built to detect as wellas to manipulate spins of atoms. 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.
