激光等离子体辐射不透明度的细致模型

Line-by-line studies on the radiative opacity of laser produced plasmas

细致谱线模型是等离子体辐射不透明度精确计算的理论方法,涉及到很多原子物理过程,需要计算大量的、精确的原子参数.在高温、稠密等离子体环境下,谱线展宽、组态相互作用、电离能下降等效应与不透明度的准确计算密切相关.文章重点介绍了目前作者在辐射不透明度细致谱线模型研究方面取得的进展情况,并且与国内外典型的实验和理论结果进行了对比.

The line-by-line model for the accurate calculation of plasma opacity requires massive accurate atomic data to deal with the detailed absorption lines. In a hot dense plasma, the effects of line broadening, configuration interaction and the ionization potential depression have great influence on the accurate calculation of plasma opacities. We report the major research progress we have obtained in the past few years, with detailed comparisons between our results and various typical experimental measurements and the results of other statistical models.
