LASER SPECTROSCOPY OF HOLMIUM AND DYSPROSIUM OXIDES

Author Institution: Department of Physics, University of New Brunswick; Department of Chemistry, Massachusetts Institute of Technology; Air Force Geophysics Laboratory, Hanscom Air Force BaseLast year (paper TB3) we reported preliminary results on Holmium Oxide (HoO) and discussed the energy linkages between the electronic states. In this paper, we shall present the results of the rotational analysis and the analysis of the hyperfine structure. We shall also discuss preliminary results of recent laser induced fluorescence experiments on Dysprosium Oxide (DyO). Resolved fluorescence spectra have provided energy linkages between several low lying states. High resolution excitation spectra show the four abundant Dy isotopes and the hyperfine structure on the two which have nuclear spin. The results of the rotational analysis will be presented and discussed in relation to Ligand Field Theory predictions
