电子贴附解离过程中的物理和化学

电子贴附解离是低能量电子与分子碰撞的重要过程,涉及电子与靶分子的相互作用、电子-分子共振态、瞬态负离子分子的解离动力学等基础物理和化学问题.本文对近年来该领域的重要进展,特别是基于负离子速度成像方法的实验研究,进行了阶段性总结,并对其未来发展方向和潜在应用进行了讨论.

Physics and Chemistry in Dissociative Electron Attachments

Dissociative electron attachment is an important process of low-energy electron collision with molecule.This process shows some fundamental features on physics.and chemistry,such as electron-target interaction,electron-molecule resonance,dissociation dynamics of temporary negative molecular ion.Here we report recent progresses on this topic during the last decade,in particular,by using anion velocity map imaging technique,and the developments and applications in the future are discussed.
