On Dielectronic Recombination
The derivation of a general formula for the coefficient of dielectric recombination is reviewed, and approximate formulae known in the literature are discussed. With the aid of Burgess' simplified formula calculations of the coefficient of dielectronic recombination for the elements C, 0 , Ne, M g , Si, S and Fe in the temperature range 108 — 4 x 106 ° K are performed. The results are presented...
متن کاملDielectronic Recombination: an Overview of Theory and Experiment, and Some Astrophysical Implications
The status of dielectronic recombination (DR) rate coefficients used for modeling cosmic plasmas is discussed. A brief overview of theoretical and experimental studies of DR is given. Results are shown which demonstrate the astrophysical importance of accurate DR rates for studies of the intergalactic medium.
متن کاملRelativistic, QED and nuclear effects in highly charged ions revealed by resonant electron-ion recombination in storage rings
Dielectronic recombination (DR) of few-electron ions has evolved into a sensitive spectroscopic tool for highly charged ions. This is due to technological advances in electron-beam preparation and ion-beam cooling techniques at heavy-ion storage rings. Recent experiments prove unambiguously that DR collision spectroscopy has become sensitive to 2nd order QED and to nuclear effects. This review ...
متن کاملDielectronic satellite spectra of heliumlike iron and nickel from the unified recombination method
It is shown that resonances in the unified recombination cross sections correspond directly to dielectronic satellite spectra. Positions, intensities, and profiles of satellite lines may be obtained accurately using the Breit-Pauli R-matrix method and the unified theory of total electron-ion recombination. The intrinsic dielectronic resonance strength corresponding to autoionizing resonances is...
متن کاملExperimental N v and Ne viii low - temperature dielectronic recombination rate coefficients
The dielectronic recombination rate coefficients of N v and Ne viii ions have been measured at a heavy-ion storage ring. The investigated energy ranges covered all dielectronic recombination resonances attached to 2s → 2p (∆n = 0) core excitations. The rate coefficients in a plasma are derived and parameterized by using a convenient fit formula. The experimentally derived rate coefficients are ...
