混合不透明度码SCO-RCG：最新进展
The hybrid opacity code SCO-RCG: recent developments
摘要：
多电荷离子等离子体的吸收谱和发射谱包含大量的电子组态和电偶极线，可以用全局方法处理。然而，一些过渡阵列仅由一小束线组成。为此，我们开发了混合不透明度代码SCO-RCG结合（统计）超跃迁阵列方法和（详细）精细结构计算（需要对角化的哈密顿矩阵）的原子结构。为了决定是否有必要对线进行详细的处理，并确定统计方法的有效性，该代码涉及考虑到过渡阵列中的线和孔隙度（局部缺失线）的合并的标准。详细的过渡阵列（斯莱特，自旋轨道和偶极积分）的计算所需的数据提供的超级配置代码SCO，它考虑到等离子体屏蔽波函数的影响。然后用Cowan程序计算了能级能量和谱线。不需要或不可能进行详细处理的跃迁阵列通过SCO中使用的UTA（未解析跃迁阵列）和STA（超级跃迁阵列）形式化在统计上描述。最新的发展，如PRTA（部分分辨跃迁阵列）模型的混合方法的扩展，以及与实验光谱（激光或Z箍缩）的比较。
英文摘要：
Absorption and emission spectra of multicharged-ion plasmas contain a huge number of electron configurations and electric-dipolar lines, which can be handled by global methods. However, some transition arrays consist only of a small bunch of lines. For that reason, we developed the hybrid opacity code SCO-RCG combining the (statistical) super-transition-array method and the (detailed) fine-structure calculation (requiring the diagonalization of the Hamiltonian matrix) of atomic structure. In order to decide whether a detailed treatment of lines is necessary and to determine the validity of statistical methods, the code involves criteria taking into account coalescence of lines and porosity (localized absence of lines) in transition arrays. Data required for the calculation of detailed transition arrays (Slater, spin-orbit and dipolar integrals) are provided by the super-configuration code SCO, which takes into account plasma screening effects on wavefunctions. Then, level energies and lines are calculated by Cowan's code. Transition arrays for which a detailed treatment is not required or impossible are described statistically, by UTA (Unresolved Transition Arrays) and STA (Super Transition Arrays) formalisms used in SCO. Recent developments are presented, such as the extension of the PRTA (Partially Resolved Transition Array) model to the hybrid approach, as well as comparisons with experimental spectra (laser or Z-pinch).
