Notes. The first column indicates the (unique) level index, and the second the configuration. The third column indicates the mixing of the levels. For example, level No. 3 is due by 84% to the 3P2 and by 12% to the 1D2 (level No. 4). Level No. 7 is due by 82% to the 3s 3p33D1 and by 10% to level No. 23 (from the third configuration in energy order, the 3s2 3p 3d), the 3D1. 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 with Eexp. Only a selection of levels is shown, the lowest 27 and the few with known experimental energies. The experimental energies are from the NIST compilation, with a few exceptions: F98: Feldman et al. (1998); T06: Trigueiros et al. (2006), confirmed here; N indicates a level with a new experimental energy, and TN with a tentative new one.
