Abstract

The Thomas-Kuhn-Reiche oscillator strength sum rule is analyzed for the case of ionized atoms in warm dense plasmas: The statistical summation of the bound-bound and the bound-free oscillator strength is proportional to the average bound electrons. This sum rule is checked for approximated absorption spectra like the detailed line accounting, detailed configurations accounting, the super transition arrays and the average atom using the CRSTA code. We show that the sum rule is properly satisfied for various elements in ranges of temperature-density that have sufficient bound orbitals. On the other hand, for the cases of few bound orbitals, the sum-rule is poorly satisfied, like in the case of high density and low temperature.

暖稠密等离子体中离子束缚电子的托马斯-库恩-雷切总和法则

针对暖稠密等离子体中电离原子的情况，分析了托马斯-库恩-雷切振荡器强度总和规则：束缚振荡强度和无束缚振荡强度的统计求和与平均束缚电子成正比。我们使用 CRSTA 代码对近似吸收光谱（如详细线描述、详细构型描述、超级转变阵列和平均原子）进行了检验。结果表明，在温度-密度范围内，具有足够结合轨道的各种元素都能正确满足和规则。另一方面，在结合轨道较少的情况下，总和规则的满足程度较低，例如在高密度和低温的情况下。

期刊介绍： High Energy Density Physics is an international journal covering original experimental and related theoretical work studying the physics of matter and radiation under extreme conditions. ''High energy density'' is understood to be an energy density exceeding about 1011 J/m3. The editors and the publisher are committed to provide this fast-growing community with a dedicated high quality channel to distribute their original findings. Papers suitable for publication in this journal cover topics in both the warm and hot dense matter regimes, such as laboratory studies relevant to non-LTE kinetics at extreme conditions, planetary interiors, astrophysical phenomena, inertial fusion and includes studies of, for example, material properties and both stable and unstable hydrodynamics. Developments in associated theoretical areas, for example the modelling of strongly coupled, partially degenerate and relativistic plasmas, are also covered.
