We present spectroscopic measurements and detailed theoretical analysis of inner-shell $LMn$ and $LNn$ ($n\ensuremath{\ge}$ 4) dielectronic resonances in highly charged $M$-shell ions of tungsten. The x-ray emission from ${\mathrm{W}}^{49+}$ through ${\mathrm{W}}^{64+}$ was recorded at the electron-beam ion trap (EBIT) facility at the National Institute of Standards and Technology with a high-purity Ge detector for electron-beam energies between 6.8 and 10.8 keV. The measured spectra clearly…

Dielectronic and radiative recombination of Si- to N-like tungsten ions

We have performed x-ray spectroscopic measurements of the dielectronic recombination resonance strength for the LMn (n = 3, ..., 10) series of Si-like W60+ to N-like W67+ tungsten ions. Highly

Extreme-ultraviolet spectroscopy of highly charged xenon ions created using an electron-beam ion trap

Extreme-ultraviolet spectra of xenon ions have been recorded in the 4.5 to 20 nm wavelength region using an electron beam ion trap and a flat field spectrometer. The electron beam energy was varied

Recombination of W19+ ions with electrons: Absolute rate coefficients from a storage-ring experiment and from theoretical calculations

We present experimentally measured and theoretically calculated rate coefficients for the electron-ion recombination of W18+([Kr]4d104f10) forming W17+. At low electron-ion collision energies, the

Relativistic many-body calculations of energy levels, hyperfine constants, electric-dipole matrix elements, and static polarizabilities for alkali-metal atoms

Removal energies and hyperfine constants of the lowest four $ns,$ ${\mathrm{np}}_{1/2},$ and ${\mathrm{np}}_{3/2}$ states in Na, K, Rb, and Cs are calculated; removal energies of the $n=7\char21{}10$

Dielectronic recombination of lanthanide and low ionization state tungsten ions: W13+–W1+

The experimental thermonuclear reactor, ITER, is currently being constructed in Cadarache, France. The reactor vessel will be constructed with a beryllium coated wall, and a tungsten coated divertor.

Dielectronic recombination of Ne-like tungsten

Relativistic calculations of the dielectronic recombination (DR) cross section and rate coefficient for Ne-like tungsten $({\mathrm{W}}^{64+})$ in the ground state ${2s}^{2}{2p}^{6}$ are performed.

Dielectronic Recombination of Br-Like Tungsten Ions

Accurate data for dielectronic recombination of tungsten ions are essential in the modeling of tungsten impurity transport and radiative power loss in International Thermonuclear Experimental Reactor

The result confirms again that the simple angular momentum averaged procedure can be effective in treating DR for heavy open-shell ions when the energy resolution is not high.
