ANGULAR DISRUPTIONS, KINETIC ENERGY DISTRIBUTIONS, AND EXCITATION FUNCTIONS OF FAST METASTABLE OXYGEN FRAGMENTS FOLLOWING ELECTRON IMPACT OF CO2

摘要

Dissociative excitation of CO2 by electron impact has been studied using the methods of translational spectrosocpy and an angular distri¬bution analysis. Earlier time-of-flight studies revealed two over-lapping spectra, the slower of which has been attributed to metastable CO(a3 π) fragments. The fast peak is the focus of the present study.nThreshold energy, angular distribution and improved time-of-flightnmeasurements indicate that the fást peak actually consists of fivenoverlapping features.
