Abstract
The experimental energy levels and values of the low even configurations , , and of Hf ii, are compared with the theoretical formulas for intermediate coupling with configuration interaction. The energy levels are in good agreement, while the mean error is less than 0.7 percent of the configuration width; the agreement between calculated and observed values is satisfactory.
