Transitions of Zn xxii, Zn xxiii, Zn xxiv, Ge xxiv, and Ge xxv observed in laser-produced plasmas

Wavelengths and energy levels are given for zinc lines of the F i, O i, and N i isoelectronic sequences, and for germanium lines of the F i and O i sequences, for transitions of the type 2s22pk–2s2pk+1. These lines were observed just below 100 Å in spectra of laser-produced plasmas. Copper and gallium lines are interpolated using the zinc and germanium wavelengths and the lines of nickel previously reported. The derived energy levels in the F i and O i sequences for zinc and germanium are compared with semiempirical predictions of Edlén.
