Pulsed magnetic fields of ∼270 kG which are repeatable to <1% from pulse to pulse have been used to produce the Zeeman effect in a number of electronic transitions for O ii, O iii, Si i, Si iii, Si iv, Cu ii, C i, C iii, Ca ii, Mg i, Mg ii, and B i. The reliability of the method has been checked by comparison of the resulting experimental g values both with theoretical Landé g factors and, when data exist, with earlier Zeeman work performed using conventional field strengths (∼25 kG). A total of 109 previously unpublished g values are reported, with the listings for the above, oxygen and silicon species being the more complete. The over-all uncertainty in the reported g values is believed to be in the range 1%–3%. While the magnet has been used above 400 kG in other experiments, assymetries were becoming apparent below 300 kG. Therefore, data for this work was restricted to 270 kG where strong LS coupling was observed to hold with few exceptions (primarily 3d terms of O ii). It is believed the method described should be of most utility in the determination of atomic transition types from their characteristic Zeeman patterns.

For a complete listing of the original spectroscopic data, see Ref. 2. The data are grouped by configurations. Values marked by an asterisk (*) were obtained from unresolved patterns only. Parentheses indicate values calculated from the g-sum rule (see text). The theoretical Landé values assume pure LS coupling.
The designations of atomic states are those of Moore (Ref. 4).
Except where indicated, the quoted experimental values are the averages of g calculated from both Mihul’s data and the present work. In general, the deviations from the average value are in the range ±0.01–0.02.
From Mihul’s data only.
From the present work only.
The apparent g values for these states differ considerably from the theoretical Landé values, indicating departure from LS coupling. However, the theoretical and experimental g sums involving these terms differ by only 1%.

Any deviation from the theoretical Landé values is of questionable significance, since the field patterns used in the determination of this g value are in the transition from Zeeman to Paschen–Back patterns.
