Results of intermediate-coupling calculations are given for Zn ii 3 d 9 4 s 5 s and Ag i 4 d 9 5 s 6 s . A [(4 d 9 ) J i , (5 s 6 s ) J ii ] J coupling scheme is appropriate for the latter. New 3 d 9 4 s ( 3 D)5 s 2 D 2½ and 3 d 9 4 s ( 1 D)5 s 2 D 2½ levels were found in Zn ii, and a few other additions and revisions are given for the analysis. The combinations of the new levels 3 d 9 ( 2 D)4 s 4 p ( 3 P°)4 F 4 1 / 2° in Zn ii and 4 d 9 ( 2 D)5 s 5 p ( 3 P°)2 F 2 1 / 2° in Ag i are also listed.
