Abstract: |
Coincidence Momentum Imaging (CMI) is a powerful imaging technique that can determine the full momentum vectors of all particles released from a single parent molecule in coincidence and thus provide detailed information on transient molecular structures. So far, the CMI technique has been extensively employed for investigating a variety of molecular reaction dynamics induced, e.g., by particle collisions, intense laser fields and synchrotron radiation. In this article, we first introduce the principle of the CMI technique, which is followed by several typical experimental designs of the CMI systems realizing the coincidence momentum detections. We then present representative examples of studying molecular reaction dynamics using the CMI technique. |
