ion kinetic energy spectrometry
1. In spectroscopy, a spectroscopic technique for analyzing the energy of ionic products produced when a beam of ions having high kinetic energy is passed through a field-free reaction chamber.
2. A spectrometric technique that uses a beam of ions of high kinetic energy passing through a field-free reaction chamber from which ionic products are collected and energy analyzed.

It is a generalization of metastable ion studies in which both uni-molecular and bi-molecular reactions are investigated.
