V. Kaufman, J. Sugar, and W. L. Rowan, "Wavelengths and energy levels of the K i isoelectronic sequence from copper to molybdenum," J. Opt. Soc. Am. B 6, 142-145 (1989)
Seven lines in the K-like transition array 3p63d–3p53d2 were observed for each of the spectra Cu xi to Mo xxiv (except for Rb and Sr) in radiation from impurity-doped tokamak and laser-generated plasmas. Wavelengths in the range of 70–112 Å, measured with an uncertainty of ±0.005 Å, are given. These are compared with calculations obtained with the relativistic Hartree–Fock code of Cowan [
R. D. Cowan,
The Theory of Atomic Structure and Spectra (
U. California Press,
Berkeley, Calif.,
1981)]. From these comparisons, predicted values for the wavelengths of Rb and Sr were obtained, with an uncertainty of ±0.01 Å.
