Abstract :
[en] The kinetic energy distribution of the O+ ions formed by dissociative ionization of O2 has been carefully examined in the range of 0.0 to 1.3 eV. In the peak at 600 meV fine structure is observed and interpreted by predissociation. The high energy side of the peak has been ascribed to the predissociation of the 2Deltag, B2Sigma-/g and the C4Sigma-/u states of O2+. The low energy side of the peak is presumably due to the predissociation of the b4Sigma-/g or the 2Phiu state of O2+ or to autoionizing predissociation.
