Dissociative ionization cross sections of CO2 at electron impact energy of 5 keV

doi:10.1088/1674-1056/23/11/113404

Abstract

The dissociative ionization of CO₂ induced by 5 keV electrons in two-body and three-body dissociative channels of CO₂²⁺ and CO₂³⁺ is identified by the ion-ion coincidence- method using a momentum imaging spectrometer. The partial ionization cross sections (PICSs) of different ionic fragments are measured and the results generally agree with the calculations made by a semi-empirical approach. Furthermore, the PICSs of the dissociative channels are also obtained by carefully considering the detection efficiency of the micro-channel plates and the total transmission efficiency of the time of flight system.

Keywords: electron collision partial ionization cross section dissociative ionization cross section momentum imaging
