摘要: 采用平均原子模型计算了Ar,Fe等离子体内电子的弹性散射微分截面。考虑了温度密度效应对微分截面的影响。结果表明,在低温低密度极限下,计算结果与可用的实验值及其它理论符合得很好,而在其它的温度密度范围内来自温度的影响比来自密度的影响更复杂,二者对电子弹性散射微分截面都产生很大影响。

关键词: 平均原子模型, 微分截面

Abstract: An average-atom(AA) model is employed to calculate differential cross sections for the elastic scattering of electrons from argon and iron plasmas.The results are in good agreement with other theoretical calculations and available experimental data in the low temperature and density limit.Numerical simulations show that the effect from temperature is more complicated than that from density,and differential cross sections change greatly with the condition of the plasma.

Key words: average-atom model, differential cross section
