| 英文摘要 | Dielectronic recombination (DR) and radiative recombination (RR) spectra of highly charged Tungsten ions are important for modeling and diagnosing magnetic fusion plasmas. We studied the DR process of Li-like W-71+(2s) ions using the flexible atomic code (FAC) based on the relativistic configuration interaction (RCI) method with Breit and QED corrections. The detailed resonance energies, widths and strengths were calculated systematically for the dominated doubly excited states (2p(1/2)nl(j))(J) (n = 19 similar to 29) and (2p(3/2)n'l(j))(J) (n' = 7 similar to 29) of Be-like W70+ ions. The contributions from the higher Rydberg states with n = 30 similar to n(cut)(n(cut) = 116) are obtained by extrapolation based on the quantum defect theory (QDT). The electron-ion recombination spectra (DR+RR), covering the center-of-mass energy range 0-1700 eV, are presented by taking into account the electron beam temperature at the experimental cooler storage ring (CSRe). It is found that the DR resonances associated with 2s(1/2) -> 2p(1/2) and 2s(1/2) -> 2p(3/2) transitions are not blending for the whole Delta n = 0 collision energy range, which will provide a good chance for testing fundamental theory clearly by experimental investigation. Finally the plasma rate coefficients are deduced from the calculated recombination spectra in the temperature range from 5.0 x 10(3) to 1.0 x 10(8) K. Compared with the AUTOSTUCTURE results, a good agreement is obtained except for the DR rates at the low electron temperature (T-e <5.0 x 10(5)K), which were mainly attributed to the difference of the first resonance group 2p(1/2)19l. The present results will guide the DR experiment of Tungsten ions at the CSRe and also be useful for ITER fusion plasmas modeling. (C) 2018 Elsevier Ltd. All rights reserved. |
