Accurate wavelengths for resonance lines of the Cu i and Zn i isoelectronic sequences for Pd to Dy

New measurements of the Cu-like and Zn-like resonance lines classified as 4s S21/2-4p P21/2,3/2∘ and 4s2 S10-4s4p P1,31∘ transitions, respectively, have been made in the range of 90–335 Å with a wavelength uncertainty of ±0.005 Å for elements Pd to Dy. The light source was the TEXT tokamak at the Fusion Research Center in Austin, Texas. The transition energies for the Zn-like lines are compared with values calculated with the multiconfiguration Dirac–Fock code of Desclaux [ Phys. Rev. A42, 5139 ( 1990)], including QED corrections. Differences between corresponding theoretical and experimental values are plotted as a function of atomic number and fitted to a smooth curve. The curve is used to obtain predicted wavelength values from Tc to U.
