- Abstract
- Absolute cross sections for electron impact formation of N2+ from N-2(+) and O-2(+) from O-2(+) have been measured in the energy range from below threshold to approximately 2000 eV. The animated crossed beams method has been employed. The cross sections at the maximum are found robe 8.4 x 10(-19) cm(2) and 12.1 x 10(-19) cm(2), respectively and the corresponding threshold energies are determined to be 43.7 +/- 0.5 eV and 36.8 +/- 0.5 eV. From an energy analysis of the collected dissociation products (N2+ and O2+), the maximum centre of mass energy available is found to be 13.0 +/- 1 eV and 14.6 +/- 1 eV, respectively.
