- Abstract
- Absolute cross sections for electron-impact dissociation of O3+ ions yielding an O+ fragment are measured. The animated electron-ion crossed-beam method is applied in the energy range from 1 eV to 2.5 keV. The maximum total cross section for O+ fragment production is found to be (3.6±0.3)×10-16 cm2 at 75 eV and such a large value of the cross section extends down to low energies. The threshold energy is found to be below 2 eV. Contributions of dissociative excitation and dissociative ionization to O+ fragment production are determined separately. The total kinetic energy release distributions are determined at select electron energies. Present data are discussed and compared with recent results [S. H. M. Deng, Phys. Rev. A 82, 062715 (2010)].
