Electron Impact Ionization and Dissociation of N3+

[摘要] Absolute cross sections for electron impact ionization and dissociation of N3+ions have been measured in a crossed-beams apparatus. In this experiment, three product ions were collected separately: N3+, N+and N2+. The single ionization process (formation of N32+) shows a threshold around 22 eV with a maximum cross section of (1.61 ± 0.01)x 10-17cm2at 120 eV. The two dissociative reactions leading to N+and N2+fragments are also analyzed in detail.
