Abstract
Ions produced by dissociative attachment in NO2 and CO2 are studied using a trochoidal monochromator as electron gun. Appearance potentials obtained for O-, O2- and NO- from NO2 are respectively 1.61+or-0.05 eV, 4.03+or-0.05 eV, 3.11+or-0.05 eV. These results are, within the experimental errors in good agreement with the (D-A) values presently known. The O-/CO2 peak near 4.4 eV shows various structures spaced by 0.12+or-0.02 eV. These structures are connected to the vibrational structure of Co2- above the CO+O- dissociation limit.Keywords
