Berechnung der Signalform bei Doppelresonanzexperimenten an2 P 3/2-Zuständen im starken Magnetfeld

A computer program has been set up, which permits to calculate the signal shape for optical double resonance experiments in² P _3/2-states of alkali atoms in a strong magnetic field. The application to the 5² P _3/2-state of³⁹K, where recently large discrepancies have been reported between early double resonance measurements and new level crossing experiments, has the following results:

1. The measured strong field spectra can be reproduced satisfactorily, if the level crossing data for the hyperfine structure coupling constants are used.
2. The computed line shifts are in good agreement with a formula recently deduced by means of a new approximation methode.
