Charge transfer reactions of some negative ions with O2 and the electron affinity of O2

Abstract

Investigations on the energy dependence of the cross section of charge transfer reactions with negative ions yield evidence on the relative values of the electron affinities of the colliding particles. It is shown that H+ O2 and SO + O2 are exothermic and that ND 2 + O2 is anendothermic reaction. With EA(H)=0.776eV, EA(SO)=1.05eV and EA (ND2) ≈ 1.2 eV we find 1.05 eV < EA (O2) < ≈ 1.2 eV.
