Calculation of the Hyperfinestructure and gJ‐Values of the 3d 4s 4p‐Configuration of Scandium

Wave functions for the 3d 4s 4p, 3d2 4p and 4s2 4p configurations of ScI are calculated, taking into account departures from SL‐coupling and configuration interaction and on fitting the radial integrals to the experimental fine structure energies. Using these wave functions gJ‐values are derived. The intermediate coupled hfs matrix elements of the 3d 4s 4p configuration are reduced to the unknown electron coupling constants as, ap and ad and calculated on estimating these constants from the spin‐orbit coupling constants and fitting them to some experimental A‐values. By this way the absolute phases of the experimental A((1P)2D)‐ and A((1P)2F)‐values are obtained. Good agreement between calculated and most experimental data has been achieved.
