摘要

研究了适合于惯性约束聚变实验和主序星内部的致密高温等离子体的离子间密度相关性和相关的筛选势。采用超网状链格式分析相关关系,通过包含部分简并和局域场校正的介电函数考虑电子的屏蔽效应。我们导出了热核反应增强率的显式解析表达式,该表达式在离子电荷为Z =1和2的等离子体的整个参数域内均适用。

Ion-Density Correlations and Enhancement of Thermonuclear Reaction Rate in Dense, Inertially Confined Fusion Plasmas
The inter-ionic density correlations and the associated screening potential are investigated for those dense, high-temperature plasmas with parameters appropriate to the inertially confined fusion experiments and the interior of main-sequence stars. The hypernetted chain scheme is used for the analysis of the correlations, where the screening effect of the electrons is taken into account via the dielectric function with inclusion of partial degeneracy and the local-field correction. We derive explicit analytic expressions for the enhancement rate of thermonuclear reactions applicable uniformly over the entire parameter domain of plasmas with the ionic charge Z =1 and 2.
