“…They classified about 150 lines and established 128 energy levels belonging to nine configurations. The analysis was extended by Neufeld [6] and Neufeld and Schrenk [7], who added 150 newly classified lines and 22 new energy levels. The Lande g J factors for 98 levels were also measured.…”

A b s t r a c t . Wave functions for the 3d 4s 4p, 3d2 4p and 4 9 4p configurations of ScI are calculated, taking into account departures from SL-coupling and configuration interaction and on fitting the radial integrals t o the experimental fine structure energies. Using these wave functions yJ-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)2P)-ralueu m e obtained.Good agreement between calculated and most experimental data has been achieved.Berechnung der Hyperfeinstruktur und der gj-Werte der 3d 4s 4p-Konfiguration des Scandiums I n h a l t s i i b e r s i c h t .

The energy levels of the scandium atom in all of its stages of ionization, as derived from the analyses of atomic spectra, have been critically compiled. In cases where only line classifications are reported in the literature, level values have been derived. Electron configurations, term designations, l-values, experimental g-values, and ionization energies are included. Calculated percentages of the two leading components of the eigenvectors of the levels are given, where available.
