Notes. The first column indicates the (unique) level index, while the second the configuration. The third column indicates the mixing of the levels. For example, level No. 8 is a due by 63% to the 3D3 and by 33% to the level No. 12, the 1F3. Only the main contributing terms (above 10%) are listed. The fourth column indicates the dominant LSJ contribution to the level. The experimental level energies Eexp (cm-1) are shown in Col. 5 while Col. 6 lists those obtained from our scattering target Et. Values in parentheses indicate differences between Eexp and Et. Only a selection of levels is shown. R are revised values, TN tentative new ones.
