【摘要】 我们应用Hooper的一阶理论计算了微观静电场几率分布,分析了该一阶理论适用的范围。计算了类氢离子的(n→1)赖曼线形。当主量子数n为奇数,赖曼线形不存在中央峰,而形成分裂的双峰。电子碰撞加宽对该双峰间距的影响是可忽略的,可应用于等离子体密度的诊断。对于翼侧线形,主要是由于微观静电场斯塔克加宽,而可忽略电子碰撞加宽,也可应用于等离子体密度的诊断。更多还原

【Abstract】 Applying the Hooper’s first-order theory, we have calculated the static micro-electric field distributions and have examined the validity of the first-order theoretical calculations. The Lyman line profiles (n→1) from hydrogenic ions have been calculated. As the principle quantum number n is odd, there is no central peak and two splitted peaks exhibit for the Lyman line profile. Electron-impact broadening has negligible effects on such sepera-rions of the splitted peaks, which are suitable for plasma density diagnostics. The Lyman line proifles in the wing regions, which are formed dominantly by the static micro-electric field distributions, can also be applied for plasma density diagnostics.更多还原
