本文综述了原子和分子氢与聚变边缘等离子体电子和离子的最重要的反应。对等离子体边缘研究中有用的所考虑的碰撞过程进行适当的表征（评估横截面、反应速率、每次碰撞的能量增益/损失等）已经执行。虽然一个完整的调查融合边缘等离子体的原子物理学将很快在其他地方，我们在这里展示了原子碰撞过程的相关性，用于描述边缘等离子体的物理状态和理解冷偏滤器等离子体的能量平衡。结果表明，激发态中性粒子在低温高密度等离子体中起着重要的作用。
A review of the most important reactions of atomic and molecular hydrogen with the fusion edge plasma electrons and ions is presented. An appropriate characterization of the considered collisions processes useful in plasma edge studies (evaluated cross sections, reaction rates, energy gain/loss per collision, etc.) has been performed. While a complete survey of atomic physics of fusion edge plasmas will be given shortly elsewhere, we demonstrate here the relevance of the atomic collision processes for describing the physical state of edge plasmas and understanding the energy balance in cool divertor plasmas. It is found that the excited neutral species play an important role in the low-temperature, high-density plasmas.
