Transitions of the type 2s–2p in highly ionized Cu, Zn, Ga, and Ge

Transitions of the type 2s–2p in the F i, O i, N i, and C i isoelectronic sequences of copper, zinc, gallium, and germanium have been identified in the spectra from plasmas produced by the omega laser system at the University of Rochester. The wavelengths are in the range 50 to 112 Å and are measured using silicon and oxygen lines as wavelength standards for gallium and using several lines from the F i, O i, and Na i isoelectronic sequences as wavelength standards for copper, zinc, and germanium. The energy levels that are determined from the measured wavelengths are also presented. Based on these measurements, the wavelengths for a number of magnetic-dipole transitions within the ground configurations of the F i, O i, and N i isoelectronic sequences are predicted.
