Froese Fischer, Method: MCHF (ab initio), Aug. 2002 Important Notice: The total energies are from spectrum calculations within a correlation model. Since different models are used for different spectra, differences of total energies between different spectra do not yield valid data. Disclaimer: In the Breit-Pauli approximation when there is significant term mixing, the velocity form of the transition operator has neglected some relativistic corrections and hence, unlike the length form, is not correct in that some terms of order \alpha^2 have been omitted. The two values are included in the .lsj files for information only and have significance when term mixing is small and the transition is spin-allowed.
