Abstract
An apparatus containing crossed molecular and pulsed electron beams has been used to obtain distributions in kinetic energy and angle of fast (≳1.5 eV) N+ and N++ ions produced through dissociative ionization of N2 by impact of electrons with energies from threshold to 300 eV. Previously unreported structure is found in both N+ and N++ kinetic energy spectra. The angular distributions of N+ (energy resolved) and N++ (total) ions are found to be substantially isotropic for electron beam–ion detector angles from 30°–110°.Keywords
