Abstract
The hyperfine structure sub-levels of the 5s5p3P1 state of cadmium are populated coherently with a 35 ps light pulse. The coherence is detected in a second excitation step resulting in a modulation of the ionization probability. A third light pulse ionizes the atom. Differences in the H.F.S. of the odd isotopes are used to selectively enhance the ionization of one isotope. In a magnetic field the Zeeman splitting of the hyperfine structure causes an additional modulation. Measurements and a theoretical interpretation are given.
