“…The combination of many-body perturbation theory and complex rotation has earlier been used to describe dielectronic recombination in several Li-like ions (see, e.g., Refs. [5,6,28,29] and references therein).…”

“…The 2p j 10l j Ј configurations are quasidegenerate and are best treated with a perturbation expansion from a so-called extended model space as has been described for Li-like fluorine in Ref. [5]. This means that the mixing among the 2p j 10l j Ј configurations is treated exactly through diagonalization of the Hamiltonian while all other configurations are included perturbatively.…”

“…On the other hand, they present an interesting case where many-body, relativistic, and QED (quantum electrodynamical) effects have to be included in a theoretical description [4][5][6][7][8] that tries to match the available experimental precision. The relative importance of relativistic and QED effects increases with increasing nuclear charge Z.…”

“…From this point of view the present Z region, where both many-body and QED effects are important, is of special interest. RMBPT calculations have already successfully described the low-energy resonances found in DR of the light lithiumlike ions C 3+ [4] and F 6+ [5] as well as in the heavy copperlike ion Pb 53+ [10] and have also been used to calculate Ar 15+ [6] and Kr 33+ [7] DR resonances at somewhat higher energies where the experimental resolution is lower and where correlation effects are thus less critical for the comparison.…”

High-resolution spectroscopy of doubly excited states produced by dielectronic recombination (DR) of lithiumlike Sc 18+ ions was performed by employing the electron-ion merged-beam technique at the heavy-ion storage ring TSR. The experimental procedure for measuring DR resonances with high precision is thoroughly described with an emphasis on the uncertainties of the experimental energy scale. Absolute measurements of recombination rate coefficients were carried out over the center-of-mass energy range 0 -50 eV that comprises all DR resonances associated with 2s 1/2 → 2p 1/2,3/2 excitations. At relative energies below 300 meV resonances due to DR via Sc 17+ ͑1s 2 2p 3/2 10l j ͒ intermediate states were found. Their positions could be measured with an uncertainty of only ±1.8 meV. The results are compared with theoretical calculations within the framework of relativistic many-body perturbation theory. By combining the precision of the experimental and theoretical results we derive a value for the 2s 1/2 → 2p 3/2 excitation energy, 44.3107͑19͒ eV, which is by more than an order of magnitude more accurate than the hitherto most precise value obtained from optical spectroscopy.

“…2p 2 excitations in Be-like ions are also more favorable compared to N 1 1s 2 ! 2s 2 or 2p 2 in He-like ions, as N 0 DR/TR resonances appear at much lower electron-ion collision energies, where storage ring measurements have their best spectral resolution [3] (N denotes the principal quantum number of a core electron, and n refers to the captured Rydberg electron).…”

Observation of Trielectronic Recombination in Be-like Cl Ions

et al. 2003

View full text Add to dashboard Cite

Recombination involving the core excitation of two electrons, which may be termed trielectronic recombination, has been experimentally identified for the first time. Using Cl13+ ions circulating in the TSR heavy-ion storage ring, we have observed surprisingly strong low-energy trielectronic recombination resonances, comparable to the dielectronic process. At higher electron-ion collision energies, trielectronic recombination is suppressed due to the autoionization of the triply excited intermediate state into excited final states. The formation of the intermediate state depends sensitively on configuration mixing, making trielectronic recombination a challenge to atomic-structure calculations.
