Zeeman effect in the perturbed 6s n d1,3D2 sequences of Ba-I: test of MQDT wavefunctions
The Zeeman effect in the 6s n d1'3D2 sequences and their 5d7d3F2,1D2 perturbers was investigated. In total 26 states were studied using Zeeman quantum-beat-and rfspectroscopy techniques. TheoreticalgJ-values obtained from an extended multi-channel quantum-defect theory are in fair agreement with the experimental results.
