Hui Li and Kenneth L. Andrew, "Need of LS-Dependent Energy Parameters in the Second Spectra of the Fifth-Group Elements*," J. Opt. Soc. Am. 62, 1476-1482 (1972)
In the analysis of As ii, the usual Slater–Condon treatment was found unsatisfactory for the multiconfiguration group 4s4p3–4p4d–4p5d–4p6d–4p7s. It was found that when LS-dependent parameters were introduced there was a substantial improvement of the agreement between experimental and calculated energy levels and for the Landé g factors as well. We carried out Hartree–Fock (HF) solutions for each term of this multiconfiguration and obtained convincing evidence of the necessity for LS-dependent parameters. In N ii, P ii, Sb 1i, and Bi ii, we found the same pattern to hold in the HF solutions for the sp3 and the corresponding first three pd configurations.

Values listed here are the ratios of the parameter values relative to that of the 3P term in each configuration.
The absolute parameter values (in units of 1000 cm−1) for the 3P terms are enclosed in parentheses.
Parameter whose value is smaller than 5 cm−1 is given a 0.00 value in units of 1000 cm−1.
