“…We have now utilized the new spectrometer to observe line emission from charge states lower than nickel-like. The new spectra compare in range of charge states to our earlier measurements on the EUV spectra of tungsten (W, Z=74) [9] (which has also been studied at the Berlin electron beam ion trap [10,11]) and gold (Au, Z=79) [12]. In both cases, the spectral data related to ion species of Rb-to Cu-like isoelectronic sequences.…”

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)

“…On the experimental side, Radtke [21] observed two allowed E1 lines belonging to the transition array of 4p 5 4d − 4p 6 (J = 1 − J = 0) for the first time at the Berlin electron-beam ion trap (EBIT), and later Utter [22] remeasured these lines and identified one more E1 line, and four other lines which were reported without classification. Around six years later, Radtke [23] measured three intra-configuration, forbidden M1 lines between 4p 5 4d-levels.…”

Abstract. Energies, transition rates, line strengths and lifetimes have been computed for all levels of the 4p 6 and 4p 5 4d configurations of W 38+ by using the multiconfiguration Dirac-Hartree-Fock method as well as relativistic many-body perturbation theory. We investigate systematically correlation, relativistic and QED effects on different properties, including excitation energies and transition rates. We demonstrate that it is important to include core-valence correlation of rather deep subshells (including 3d and 3p) to reach close to spectroscopic accuracy for the transition energies. We also show that high multipole transitions (E3, M2) are important for the lifetime of some metastable levels of 4p 5 4d ( 3 F 3 , 1 D 2 , 3 D 2 ). The present results are in good agreement with experiments and of considerable higher accuracy than what has been reached in previous theoretical works.

“…Retarded E1, E2, and E3 matrix elements are evaluated in both length and velocity forms. A detailed discussion of the various contributions to the dipole matrix elements and energy levels is given for nickellike tungsten (Z = 74), which plays an important role in tokamaks [21,22], electron beam ion traps [17,35,36], x-ray lasers [37], and z-pinches [16].…”
