路径积分在类氢等离子体中谱线展宽的应用
Application of path integral formalism to spectral line broadening: lyman alpha in hydrogenic plasma
摘要：
本文用路径积分方法重新推导了电子碰撞近似中不考虑精细结构的莱曼α线形的结果。这里提出的方法旨在提供一个量子形式主义，将处理离子和电子在相同的物理基础。这种方法的优点也在于处理的情况下，动力学的影响。因此，我们给出了一个表达式的偶极自相关函数考虑到离子动力学效应。
英文摘要：
In this paper the results of Lyman alpha line shapes without the fine structure in the electron impact approximation are rederived using a path integral formalism. The method presented here is designed to provide a quantum formalism that will treat the ions and the electrons on the same physical basis. This method has also the advantage of treating cases where the dynamical effects are present. We therefore, give an expression of the dipolar autocorrelation function taking into account the ion dynamics effects.
