The description of the plasma effect using an accurate screened potential, which is crucial for many applications of plasma physics, represents a hitherto challenge for theory. Here, we present a theoretical determination of the level delocalization and transition rate of an exemplary hydrogen atom immersed in plasmas. Specific forms of the screened potentials include the average-atom, the standard ion-sphere, and those recently proposed by Shukla and Eliasson [Phys. Rev. Lett. 108, 165007 (2012)], Akbari-Moghanjoughi [Phys. Plasmas 22, 022103 (2015)], and Stanton and Murillo [Phys. Rev. E 91, 033104 (2015)]. Calculations including these potentials are performed with a new uniform relativistic self-consistent model electron photon processes in plasmas we developed. A comparison with the five sets of results obtained from our models in a uniform background (same density or temperature regions) is presented for the first time, and deviations among each other are shown. The present results not only provide valuable information regarding plasma effects but also reveal the applicability and the limitation of these models in some regimes and pave the way toward a deeper understanding of collective behavior for atoms or ions subjected to the plasma environments.

使用各种静态屏蔽电位对等离子体环境下氢原子的水平离域和光谱进行系统研究

使用准确的筛选电位来描述等离子体效应，这对于等离子体物理学的许多应用至关重要，代表了迄今为止的理论挑战。在这里，我们提出了浸入等离子体中的示例性氢原子的能级离域和跃迁率的理论确定。筛选电位的具体形式包括平均原子、标准离子球以及最近由 Shukla 和 Eliasson 提出的那些 [Phys. 牧师莱特。108, 165007 (2012)], Akbari-Moghanjoughi [Phys. Plasmas 22, 022103 (2015)]，以及 Stanton 和 Murillo [Phys. 修订版 E 91, 033104 (2015)]。使用我们开发的等离子体中新的均匀相对论自洽模型电子光子过程进行包括这些电位的计算。首次与我们的模型在均匀背景（相同密度或温度区域）中获得的五组结果进行了比较，并显示了彼此之间的偏差。目前的结果不仅提供了有关等离子体效应的有价值的信息，而且揭示了这些模型在某些情况下的适用性和局限性，并为更深入地了解原子或离子在等离子体环境下的集体行为铺平了道路。
