Abstract

The bottom three J = 1 K II levels are nearly degenerate, leading to strong interactions among them, which requires the simultaneous presence of relativistic and correlation effects in any ab initio treatment. Relativistic configuration interaction wavefunctions with ∼10000 basis functions (J = 1) produce f-values in very good agreement with two of the three measured values. Improved predictions are made for the two uppermost J = 1 levels. Length and velocity gauge spreads average 1.3% for the five transitions. Landé g-values and hyperfine structure constants are also obtained.
