“…9 and 10 for the 2s − 2p 1/2 and 2s − 2p 3/2 transitions, respectively. Empirical results at low to mid Z come from NIST's online database of atomic spectra [36], with beam-foil measurements at Z = 47 [37], 50 and 54 [38]. At high Z, available experimental results are from electron beam ion trap (EBIT) measurements [5,[39][40][41][42].…”

A QED approach to the calculation of the spectra of the lithium isoelectronic sequence is implemented. A modified Furry representation based on the Kohn-Sham potential is used to evaluate all one-and two-photon diagrams with the exception of the two-loop Lamb shift. Three-photon diagrams are estimated with Hamiltonian methods. After incorporating recent calculations of the two-loop Lamb shift and recoil corrections a comprehensive tabulation of the 2s, 2p 1/2 and 2p 3/2 energy levels as well as the 2s − 2p 1/2 and 2s − 2p 3/2 transition energies for Z = 10 − 100 is presented.

The relativistic nuclear recoil, higher-order interelectronic-interaction, and screened QED corrections to the transition energies in Li-like ions are evaluated. The calculation of the relativistic recoil effect is performed to all orders in 1/Z. The interelectronic-interaction correction to the transition energies beyond the two-photon exchange level is evaluated to all orders in 1/Z within the Breit approximation. The evaluation is carried out employing the large-scale configurationinteraction Dirac-Fock-Sturm method. The rigorous calculation of the complete gauge invariant sets of the screened self-energy and vacuum-polarization diagrams is performed utilizing a local screening potential as the zeroth-order approximation. The theoretical predictions for the 2p j − 2s transition energies are compiled and compared with available experimental data in the range of the nuclear charge number Z = 10 − 60.

This contribution reviews experimental and theoretical work on spectroscopy of tungsten published since the last critical compilation of the energy levels and spectral lines of highly ionized tungsten (Kramida and Shirai. At. Data Nucl. Data Tables, 95, 305 (2009)). Since then, 18 new experimental studies were published, which resulted in new identifications and (or) significantly improved wavelengths of spectral lines and energy levels of Li-like through As-like and Pm-like tungsten. A few tens of theoretical studies of tungsten spectra were published since 2008. A number of them report on high-precision calculations of energy levels, transition wavelengths, and radiative rates for tungsten spectra, such as neutral tungsten, Yb-like, Rh-like through Rb-like, Ag-like, Ga-like, Zn-like, Ni-like, Ca-like, Al-like, Mg-like, Na-like, Ne-like, B-like, Be-like, and Li-like. These developments are reviewed. Based on new experimental data, systematic errors are removed from some of the earlier measurements. Some new data are obtained by analyzing publications of other authors. Based on new published theoretical data, some old experimental results were confirmed and assessed. Revised and extended tables of energy levels and spectral lines of highly ionized tungsten are presented. PACS Nos: 32.10.Fn, 32.30.-r, 32.30.Jc, 32.30.Rj Résumé : Nous passons ici en revue les travaux expérimentaux et théoriques sur la spectroscopie du tungstène, qui ont été publiés depuis la dernière compilation systématique des niveaux d'énergie et des raies spectrales du tungstène hautement ionisé (Kamida et Shirai. At. Data Nucl. Data Tables, 95, 305 (2009)). Depuis, 18 nouvelles études expérimentales ont été publiées, qui ont résulté en de nouvelles identifications et une amélioration significative des longueurs d'onde des raies et de l'énergie des niveaux des ions de tungstène allant du type Li jusqu'aux types As et Pm. Quelques dizaines études théoriques sur le tungstène ont été publiées depuis 2008. Certaines d'entre elles rapportent des calculs de haute précision de niveaux d'énergie, de longueurs d'onde de transitions et de taux radiatifs pour des spectres de tungstène, neutre et ionisé de types Yb, de Rh à Rb, Ag, Ga, Zn, Ni, Ca, Al, Mg, Na, Ne, B, Be et Li. Nous les passons en revue. Les mesures récentes ont permis d'éliminer certaines erreurs systématiques des mesures antérieures. Certains nouveaux résultats viennent de l'analyse de publications d'autres auteurs. Les nouveaux résultats théoriques ont permis de confirmer des résultats expérimentaux antérieurs dont l'identification restait incertaine. Nous présentons des tables nouvelles et étendues des niveaux d'énergie et des raies spectrales du tungstène hautement ionisé. [Traduit par la Rédaction]
