Zum Nachweis von änderungen im angeregten Zustand eines Atoms durch Beobachten der folgenden änderungen im Grundzustand

Radio frequency transitions in the excited state of Rb atoms are observed by measuring the transmitted light in a resonance cell experiment. The influence of additional radio frequency transitions simultaneously performed between the Zeeman sub-levels of the ground state is studied. Methods for observing signals of the excited states without using fluorescent light as detector are discussed concerning the magnetic deflection of optical oriented atoms and also the influence of recoil of the scattered light quants on the direction of an atomic beam.
