Configurations 4f^106s6p and 4f^95d6s^2 in Neutral Dysprosium†

A partial analysis of the configurations 4f106s6p and 4f95d6s2 in neutral dysprosium has been based on least-squares calculations of energy-level structures, combined with experimental data for observed energy levels, g values, and isotope shifts. Thirty-one levels for each configuration have now been interpreted; of these, 24 levels are new designations in 4f106s6p and 18 are new designations in 4f95d6s2. We were able to fit the levels of 4f106s6p to within a standard deviation equal to 0.6% of the experimental energy-level spread, and the levels of 4f95d6s2 to within 0.9%. The agreement between experimental and calculated g values is good and the configuration assignments are consistent with isotope-shift data.
