In this bachelor thesis, the energy difference between Zeeman hyper-fine substates within the Breit-Rabi diagrams of hydrogen and deuterium are measured as a function of the magnetic field. Thereby a recently discovered effect is exploited, where atoms passing through the sine-like magnetic field of a Sona-transition unit experience in their inertial system an electromagnetic wave. The Energy of the corresponding photons depends on the atomic velocity and the Sona wavelength. If two neighboring Zeeman states have an energetic difference equal to an odd multiple of the single-photon energy, there is a resonance that can transfer atoms from one state to the other. These resonances can be observed when the occupation numbers are measured as a function of the magnetic field strength in the Sona-transition unit, because the energy difference of the Zeeman states depends on an external magnetic field. Since the energy difference between the Zeeman states is 0 in absence of a magnetic field, the peaks can be counted to determine the energy difference associated to a peak. Because the single photon energy or the effective wavelength and the effective magnetic field in the Sona transition cannot be easily measured, they must be calibrated using the theoretical Breit-Rabi diagram. Due to the fact, that energy of the α2β3-transition of hydrogen and the α3β4-transition of deuterium increases linearly in first order, the calibration can be better determined if both α1α2-transition of hydrogen and deuterium and the α2α3-transition of deuterium are also included. Since the peaks of the α1α2-and α2α3-transitions of deuterium cannot be identified well in the data, the effective wavelength determined for hydrogen is used in the analysis of deuterium and only the calibration of the magnetic field is redetermined. |
