Lande gJ factor measurements in the 6snd(1),D-3(2) sequences of Yb I

In English The Lande g(J) factors in the 6snd(1,3)D(2) sequences as well as states from the perturbing configurations of neutral Ytterbium have been measured by time-resolved fluorescence spectroscopy. Strong singlet-triplet mixing effects were observed. The g(J) factors were measured using the Zeeman quantum-beat technique following step-wise laser excitation. The experiment provided new data for checking the Multi-channel Quantum Defect Theory (MQDT) used in energy-level and lifetime analysis.
