不同温度下类Li氖等离子体光谱模拟（英文）

Spectrum Simulation of Li-like Neon Plasma at Different Temperature

在FAC(flexible atomic code)程序包的碰撞辐射模型的基础上,模拟了碰撞电离平衡状态下的类Li氖等离子体的X射线发射光谱。并将双电子复合(DR)、辐射复合(RR)、碰撞电离(CI)和级联效应等过程的速率系数与其他文献的结果进行了比较,误差在20%以内,发现这些过程和碰撞激发(CE)过程一样重要,在光谱模拟过程中不能被忽略。此外,还分析了类Li氖等离子体温度与各动力学过程和光谱相对强度之间的关系,且模拟得到的谱线强度能敏感地反应氖等离子体的电子温度。

The synthetic X-ray spectra emitted from Li-like neon plasma are simulated in the collisional ionization equilibrium by the flexible atomic code (FAC). The rate coefficients of the dielectronic recombination (DR), radiative recombination (RR), collisional ionization (CI) and cascade are compared with the previous data, and the differences between current and previous data are less than 20%. These processes are as important as collisional excitation (CE) and can t be ignored in spectra simulation. In addition, the relationship between the temperature of the Li-like plasma and the relative dynamics of each kinetic process and spectrum is also analyzed, and the simulated line intensity can sensitively reflect the electron temperature of the neon plasma.
