摘要
利用改进后的Ｍｏｒｅ模型计算Ａｎ等离子体各电离度离子的Ｅｉｎｓｔｅｉｎ系数和线发射强度。在０．３５μｍ激光与金平面靶耦合产生晕区等离子体条件下，求解离子模型定态速率方程组得到离子布居概率，从而求出Ｘ光线发射能谱。将此能谱与ＪＢ１９程序计算得到的出系统外边界光子能谱进行了比较。
The Einstein coefficients and line-emission intensities of An ions are calculated with an improved More model. The population of the ions and the X-ray emission spectrum are given by solving stationary H-like ionmodel rate-equations for the corona plasma produced by coupling of laser with An target. The spectrum is compared with the photon that obtained by multi-group photon diffusion code JB19 simulation.
