Notes

1Two broad groups of partially resolved bands, no vibr. assignments.
2The transition energy is close to the difference of He+ + Kr and He + Kr+ which is 85396. See note c of HeAr+.
3Arising from He + Kr+ (2P ground sate splitting 5371 cm-1).
4From He+ -off- Kr elastic scattering data Weise, 1973.
