199 Zeeman patterns are presented for Gd i, from which g-values are calculated for 118 levels. A discussion is given of the terms and electron configurations to which previously unassigned even levels may belong; new assignments are given for 15 even levels belonging to four terms (7P, 9F, 9D, 7D) of the configuration . Russell’s prediction that the next even configuration, , begins at ~25 000 cm−1 is confirmed. The observed g-values in general lie within ±5% of the L–S coupling values, but marked deviations occur for some levels, indicating that energy-level mixing is present.
