In a magnetic field, the states of the hyperfine structure split according to their possible magnetic projections, into the so-called Zeeman states. The splitting of these energy levels in a hydrogen-like atom by an applied magnetic field is described by the Breit-Rabi formula. In this thesis, the transitions between different hyperfine energy levels of excited atoms (such as hydrogen and deuterium) in a magnetic field are studied. The main objective is to investigate the influences that can be taken on these transitions. At the Institute for Nuclear Physics of Forschungszentrum Jülich, measurements of the hyperfine structure and its substates are performed using a Lambshift polarimeter and a novel Sona transition unit. Here, a static magnetic field in the form of a harmonic oscillation is used to generate photons in the inertial system of the through-going particle to induce transitions between Zeeman states of the hyperfine structure in an atomic beam. It is important to note that the relative velocity of the photons corresponds to the relative velocity of the atoms in the beam. For hydrogen, this simultaneously exchanges the occupation numbers of the α1 and β3 states according to the principle of P.G. Sona, since their precession cannot follow the magnetic field and the magnetic moment reverses its orientation relative to the applied field of the quantization axis after the zero crossing. In a Spinfilter behind the Sona region, the states can be filtered again, leaving only one atoms in a single state in the beam. Atoms in the remaining excited states are converted to the ground state by a static electric field at the end of the beam path in the quench chamber. During this process, Lyman-α photons are emitted that are then converted into an electrical signal in a photomultiplier. This signal is proportional to the number of excited atoms and, thus, allows conclusions about the rearrangement of the various states during the transitions. This thesis deals with the evaluation of the measurement setup and its influences on the measurement. Furthermore, a model with two transition possibilities was developed to explain the oscillations, and for the first time, a scaling of the measurement result in the energy image was performed.
