自60年前Bates提出直接解离重组机制以来，特别是在过去的30年里，已经有了许多重要的理论进展。由于篇幅有限，无法回顾所有重要的理论贡献。相反，我对一些选定的事态发展发表评论。重点讨论了早期的DR散射理论和强大的多通道量子亏损理论（MQDT）。后一种方法的增强包括增加了二阶和所有阶K矩阵，离子旋转运动，里德堡态与激发核和里德堡态之间的自旋-轨道耦合。还讨论了玻恩-奥本海默击穿引起的双原子光散射、双原子光散射中的角积分布和光散射截面的振荡。
Since the proposal, sixty years ago, of the direct dissociative recombination (DR) mechanism by Bates, there have been many important theoretical advances, especially within the past 30 years. Space limitations preclude the review of all significant theoretical contributions. Instead, I comment upon a few selected developments. Highlights of the early scattering theory of DR and of the powerful Multichannel Quantum Defect Theory (MQDT) are discussed. Enhancements to the latter approach have included the addition of second and all order K matrices, ion rotational motion, Rydberg states with excited cores and spin-orbit coupling between Rydberg states. Also discussed are DR by Born-Oppenheimer breakdown, angular product distributions in diatomic DR and oscillations in DR cross sections.
