“…For H-like Ar at 9500 eV electron beam energy, equations (A.5a)-(A.5c) give σ rr = 1.2 × 10 -23 cm 2 . This is approximately a factor of 2 lower than the relativisitic Dirac-Fock value calculated by Trzhaskovskaya et al [45].…”

Atomic spectroscopy results from the electron beam ion trap at the National Institute of Standards and Technology have generally agreed with the predictions of theory extremely well. An interesting exception is our recent result on the helium isoelectronic sequence at Z = 22, which agrees instead with a meta-analysis of all prior measurements above Z = 15, but disagrees with both theory and a contemporaneous report of an independent measurement at Z = 18 which claims to validate theory to high accuracy. Here, a potential systematic shift involving high-n satellite lines induced by double charge exchange is quantitatively estimated and shown to be potentially significant in experiments involving gasses. Suggestions for further refinements in estimating the magnitude of this systematic shift are given.

“…Results have been published for the isoelectronic sequences from H-like to Mg-like [23, and references therein]. Rate coefficients for non-resonant radiative recombination (RR) are also available [24,25]. Independently, Gu calculated DR and RR rate coefficients for selected ions of astrophysical interest [26][27][28].…”

This review summarizes the present status of an ongoing experimental effort to provide reliable rate coefficients for dielectronic recombination of highly charged iron ions for the modeling of astrophysical and other plasmas. The experimental work has been carried out over more than a decade at the heavy-ion storage-ring TSR of the Max-Planck-Institute for Nuclear Physics in Heidelberg, Germany. The experimental and data reduction procedures are outlined. The role of previously disregarded processes such as fine-structure core excitations and trielectronic recombination is highlighted. Plasma rate coefficients for dielectronic recombination of Fe q+ ions (q=7-10, 13-22) and Ni 25+ are presented graphically and in a simple parameterized form allowing for easy use in plasma modeling codes. It is concluded that storage-ring experiments are presently the only source for reliable low-temperature dielectronic recombination rate-coefficients of complex ions.
