Measurement of the D -line doublet in high- Z highly charged sodiumlike ions

We report a direct observation of the D-line doublet of Na-like ions with Z{>=}72. Spectra in the 1-9 nm spectral range are presented showing the widely split doublet for Hf{sup 61+}, Ta{sup 62+}, W{sup 63+}, and Au{sup 68+}. The ions were produced and confined in an electron-beam ion trap and ob...

Description
Summary:	We report a direct observation of the D-line doublet of Na-like ions with Z{>=}72. Spectra in the 1-9 nm spectral range are presented showing the widely split doublet for Hf{sup 61+}, Ta{sup 62+}, W{sup 63+}, and Au{sup 68+}. The ions were produced and confined in an electron-beam ion trap and observed with a flat-field grazing incidence spectrometer. The measured wavelengths agree well with the predictions of relativistic many-body perturbation theory with QED corrections. We also report the measured wavelengths for several transitions in Si-, Al-, and Mg-like ions of Hf, Ta, and W and in Mg-like Au.
