The energy levels and spectral lines of multiply ionized tungsten atoms, W2+ through W73+,
have been compiled. Experimental data on spectral lines and energy levels exist for the …

The possibility of using extreme ultraviolet emission from low charge states of tungsten ions
to diagnose the divertor plasmas of the ITER tokamak has been investigated. Spectral …

The extreme ultraviolet (EUV) emission from few-times ionized tungsten atoms has been
experimentally studied at the Livermore electron beam ion trap facility. The ions were …

We present a direct observation of the M1 transition between the fine structure splitting in the
4 f 13 5 s 2 5 p 6 2 F ground term of W VIII. The spectroscopic data of few-times ionized …

The wavelength and rate of the 5 p-5 s transition of W xiv–W xvi ions have been calculated
by the relativistic configuration interaction method with the implementation of the flexible …

Tungsten spectra excited in the vacuum sparks of different setups and electric circuits were
recorded on two high-resolution vacuum spectrographs. For the region 190–500 Å, a 10 m …

The results obtained on the W VIII spectrum as well as on the isoelectronic spectra Lu V, Hf
VI, Ta VII, and Re IX in the VUV wavelength region are summarized with emphasis on the …

Spectra of hafnium, tantalum, tungsten, and rhenium in the range of 145–350Å, excited in a
low-inductive vacuum spark, have been recorded on a grazing-incidence vacuum …

We have measured extreme ultraviolet spectra from tungsten ions in the 20 nm region in
plasmas produced in the Large Helical Device at the National Institute for Fusion Science …

Atomic physics has played an important role throughout the history of experimental plasma
physics. For example, accurate knowledge of atomic properties has been crucial for …
