Recently, the existence of extremely energetic hydrogen atoms in electrical discharges has been proposed in the literature with large controversy, from the analysis of the anomalous broadening of hydrogen Balmer lines. In this paper, the velocity distribution of H atoms and the profiles of the emitting atom lines created by the exothermic reaction H2++H{2}→H{3}{+}+H+ΔE are calculated, as a function of the internal energy defect ΔE . The shapes found for the non-Maxwell-Boltzmann distributions resulting in non-Gaussian line profiles raise serious arguments against the existence of hot and superhot H atoms as it has been proposed, at least with those temperatures.
最近，从氢巴尔末线异常展宽的分析来看，文献中对于放电过程中是否存在极高能量的氢原子存在很大争议。本文计算了H原子的速度分布以及由放热反应H₂⁺ + H₂ → H₃⁺ + H + ΔE产生的发射原子线的轮廓，作为内能缺陷ΔE的函数。发现非麦克斯韦 - 玻尔兹曼分布导致非高斯线型，这对如所提出的热和超热H原子的存在提出了严重质疑，至少在那些温度下是如此。
