| 摘 要： | 使用平均原子模型研究了电四极及更高阶跃迁对高温稠密金等离子体辐射不透明度的贡献.计算并讨论了在不同温度密度条件下,电四极,电八极,电十六极跃迁对束缚-束缚跃迁的影响.计算了密度为96.405 g/cm3时,不同温度条件下,电四极,电八极跃迁对Rosseland平均不透明度的贡献.考虑了电四极、电八极跃迁后金等离子体不透明度的相对改变最大分别为4.67%和1.5%,并和其它文献的理论结果进行了比较.

| Abstract: | The contributions of the multipole transitions to the opacity of hot and dense plasmas of gold are taken into account by using an average-atom model.The influence of the E2,E3 and E4 transitions on the bound-bound opacity are discussed,respectively.The isodense opacity at a density of 96.405 g/cm~3 is taken as an example to show the influences of the E2 and E3 transitions to the Rosseland mean opacity.It shows that the Rosseland mean opacity increases 4.67% and 1.5% when the E2 and E3 transitions are included,respectively. |
