Abstract
From measurements of the relative abundances of O-and CO3-ions produced in carbon dioxide by electron attachment and subsequent ion-molecule reactions, and from current-growth data, values of the primary ionization coefficient, attachment coefficient and rate coefficient for the reaction O-+2CO2to CO3-+CO2have been obtained for 60*10-17-17V cm2at gas number densities N between 0.2 and 5.0*1016cm-3.
