摘要:

利用SHML模型计算了密度为ρ=1g•cm-3、温度为150eV、200eV、250eV、300eV、400eV的Sn等离子体的随光子能量变化的辐射不透明度及Rosseland平均不透明度。分析了不透明度随光子能量变化曲线的吸收峰值(不透明度峰值)与能级跃迁的对应关系。还将Sn的Rosseland平均不透明度与DCA/UTA及STA模型计算结果作了比较,吻合较好。

Abstract:

By SHML model, the frequency-dependent opacity and the Rosseland mean opacity for Sn plasma at high temperature (150eV, 200eV, 250eV, 300eV, 400eV) and density (ρ=1g•cm-3) are calculated. The relationship between the absorption peaks (the opacity peaks) of curve of frequency-dependent opacity and the transitions are explained. The results are in good agreement with theoretical calculations using DCA/UTA and STA model.
