Spectra of Ions in the Fluorine i Isoelectronic Sequence from Sc xiii to Cu xxi

In a study of the spectra of ions Sc xiii to Cu xxi in the fluorine isoelectronic sequence, lines of the 2p5–2p4 3s and 2p5–2p4 3d arrays have been observed and classified, as well as some lines of the 2s 2p6–2s2p5 3s array. Assignments were made on the basis of extrapolations and an intermediate-coupling calculation. The results are compared with those available in the literature.
