Abstract
The dielectronic recombination (DR) of neonlike gold ions is investigated employing the flexible atomic code based on the relativistic configuration interaction method, and its influence on the ionization balance and radiation energy in high-temperature plasma is also studied. The total resonance strength for LMM configuration complex is in a good agreement with the experimental measurement and other theoretical works. The DR rate coefficients are calculated and compared with the three-body recombination and radiative recombination rate coefficients. The DR process is the dominant recombination mechanism of Ne-like gold ions for plasma with temperature Te≥6.5 keV and density ne≤2×1022 cm-3, which is close to the condition of X-ray conversion region in the inertial confinement fusion. Moreover, the DR satellite spectra of LMM, LMN and LMO resonances are simulated, and compared with the intensities of the corresponding resonance lines induced by the electron impact excitation. The intensity ratio of the satellite line 3D’ \([(2p^{5}_{3/2}3d_{3/2}3d_{5/2})_{J=5/2}\)–\((2p^{6}3d_{3/2})_{ J=3/2}]\) and the resonance line 3D \([(2p^{5}_{3/2}3d_{5/2})_{J=1}\)–\((2p^{6})_{J=0}]\) is given, which can be applied for diagnostics of plasma temperature.
