“…All electric and magnetic dipole and quadrupole radiative transitions as computed by HUL-LAC were taken into account. Previous work with W spectra from these charge states has shown that electric-dipole -forbidden transitions in this spectral range can be quite bright for the temperature and density conditions of the present experiments [20,21]. The results of the calculations for Th and U are summarized in Figs.…”

Systematic variation of the electron-beam energy in an electron-beam ion trap has been employed to produce soft-X-ray spectra of Os, Bi, Th, and U with highest charge states ranging up to Ni-like ions. Guided by relativistic atomic structure calculations, the strongest lines have been identified with ∆n=0 (n=4 to n =4) transitions in Rb-to Cu-like ions. The rather weak 4p-4d transitions are much less affected by QED contributions than the dominant 4s-4p transitions. Our wavelength measurements consequently provide benchmarks with and (almost) without QED. Because the radiative corrections are not very sensitive to the number of electrons in the valence shell, our data, moreover, provide benchmarks for the evaluation of electron-electron interactions.Résumé francais: (traduit par le journal)

“…The level energies for such ions determined in the QR approach are presented in [13]. That work contains the overview of various studies of the tungsten ions and the comparison of our QR results with available data [8,11,12,[14][15][16][17][18][19]. In the very recent work [20] the multiconfiguration Dirac-Hartree-Fock method (MCDHF) is applied to determine level energies and radiative lifetimes for eight Kr-like ions, including the W 38+ ion.…”

The ab initio quasirelativistic approximation was used to derive transition data for the multicharged tungsten ions W 38+ -W43+ with an open 4p shell. The configuration interaction method with transformed radial orbitals was applied to include electron correlation effects. The relativistic effects were taken into account in the Breit-Pauli approximation for the quasirelativistic Hartree-Fock radial orbitals. The level energies E, radiative lifetimes τ, and Landé g-factors were calculated for the 4s 4d, and 4s4pN+1 configurations of six tungsten ions. The radiative transition wavelengths λ, spontaneous emission transition probabilities A and their uncertainties for the electric dipole, electric quadrupole, electric octupole, magnetic dipole and magnetic quadrupole transitions among the levels of these configurations are presented.
