论文摘要
我们介绍了一项详细的研究，该研究基于超透明坐标的经典轨迹计算，氢和氘等离子体中的离子原子三体重组。由于远程带电诱导的偶极相互作用的主要作用，我们的结果表明H $ _2^+$和D $ _2^+$分别是氢和氘等离子的主要反应产物。此外，当碰撞能超过分子离子的解离能时，我们发现了更陡峭的能量依赖性反应速率，从而进入了以短距离相互作用为主的新的动力学状态。
We present a detailed study about ion-atom-atom three-body recombination in hydrogen and deuterium plasmas based on classical trajectory calculations in hyperspherical coordinates. Our results, due to the predominant role of the long-range charged-induced dipole interaction, indicate that H$_2^+$ and D$_2^+$ are the main reaction products in the case of hydrogen and deuterium plasmas, respectively. Besides, we find a more steep energy-dependent reaction rate when the collision energy surpasses the dissociation energy of the molecular ion, thus entering a new dynamical regime dominated by short-range interactions.
