采用FAC(flexible atomic code)程序,在细致能级层次计算等离子体原子结构参数和等离子体中各种原子物理过程的基础上,建立了等离子体中各种能级布居的速率方程,其中考虑了等离子体中各种原子物理过程的影响.通过求解基于细致能级的速率方程,计算了Z箍缩产生的Al等离子体辐射的细致能谱结构,对实验谱进行了辨认和归类,并对实验测量谱的成分做了简单分析.
In this article,the atomic structure and processes for Al are calculated in details by using the flexible atomic code.With these atomic parameters,the rate equations are established and resolved in order to obtain the level populations.The X ray radiation from Z-pinch Al plasma is then calculated.The experimental spectra are identified in details according to our theoretical results.
