Abstract
Absolute cross sections for electron impact ionization and dissociation of N 3 + ions have been measured in a crossed-beams apparatus. In this experiment, three product ions were collected separately: N 3 + , N + and N 2 + . The single ionization process (formation of N 3 2+ ) shows a threshold around 22 eV with a maximum cross section of (1.61 ± 0.01)x 10 -17 cm 2 at 120 eV. The two dissociative reactions leading to N + and N 2 + fragments are also analyzed in detail.
