Differential cross sections for electron-impact excitation of the electronic states of N2
Abstract
Differential cross sections for the electron-impact excitation of the first ten electronic states of N2 have been determined at five incident energies ranging from 15 to 50 eV. These differential cross sections were obtained for the scattering range 10°-90° by analyzing electron-energy-loss spectra in N2 at a number of fixed scattering angles within that range. The present study represents a comprehensive remeasurement of the earlier work of Cartwright and co-workers [Phys. Rev. A 16, 1013 (1977)] and was undertaken with a view to resolving certain anomalies which have been reported in the literature when the earlier cross-section set has been applied to model calculations of swarm parameters.
