3 0 M ar 2 01 7 Partial and Total Dielectronic Recombination Rate Coefficients
Dielectronic recombination (DR) is the dominant mode of recombination in magnetically confined fusion plasmas for intermediate to lowcharged ions of W. Complete, final-state resolved partial isonuclear W DR rate coefficient data is required for detailed collisional-radiative modelling for such plasmas in preparation for the upcoming fusion experiment ITER. To realize this requirement, we contin...
متن کاملExperimentally Derived Dielectronic Recombination Rate Coefficients for Helium-like C V and Hydrogenic O Viii
Using published measurements of dielectronic recombination (DR) resonance strengths and energies for C V to C IV and O VIII to O VII, we have calculated the DR rate coefficient for these ions. Our derived rates are in good agreement with multiconÐguration, intermediate-coupling and multiconÐguration, fully relativistic calculations, as well as with most L S-coupling calculations. Our results ar...
متن کاملRecombination rate coefficients for KLL dielectronic satellite lines of Fe XXV and Ni XXVII
The unified method for total electron–ion recombination is extended to study the dielectronic satellite (DES) lines. These lines, formed from radiative decay of autoionizing states, are highly sensitive temperature diagnostics of astrophysical and laboratory plasma sources. The computation of the unified recombination rates is based on the relativistic Breit–Pauli R-matrix method and the close ...
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 ...
متن کاملOn 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...
