修正的Debye-Huckel电子屏蔽和穿透因子
Modified Debye-Huckel Electron Shielding and Penetration Factor
摘要:
导出了在天体物理等离子体中反应核聚变屏蔽效应的屏蔽势,并对屏蔽势进行了非标准电子云分布修正。讨论了在空间坐标系中具有耗尽尾部的云的情况。修正屏蔽势是从基于Debye-Huckel半径倒数波动的统计力学参数和广义统计力学中使用的伯努利方程的解中得到的。提供了用于评估在任何能量下的穿透概率的图和表。
英文摘要:
Screened potential, modified by non standard electron cloud distributions responsible for the shielding effect on fusion of reacting nuclei in astrophysical plasmas, is derived. The case of clouds with depleted tails in space coordinates is discussed. The modified screened potential is obtained both from statistical mechanics arguments based on fluctuations of the inverse of the Debye-Huckel radius and from the solution of a Bernoulli equation used in generalized statistical mechanics. Plots and tables useful in evaluating penetration probability at any energy are provided.
