Abstract
We report integral cross sections (ICSs) for electron impactexcitation of the A 3Σ+u, B 3Πg,W 3Δu, B' 3Σ-u,a' 1Σ-u, a 1Πg,ω1Δu, C 3Πu,E 3Σ+g and a'' 1Σ+g electronic states of N2. The present data, for eachstate, were derived at five incident electron energies in therange 15-50 eV, from the earlier crossed-beam differentialcross section (DCS) measurements of our group. This wasfacilitated by using a molecular phase shift analysis techniqueto extrapolate the measured DCSs to 0° and 180°,before performing the integration. A comprehensive comparison ofthe present ICSs with the results of earlier experimentalstudies, both crossed beam and electron swarm, and theoreticalcalculations is provided. This comparison clearly indicates thatsome of the previous estimates for these excitedelectronic-state cross sections need to be reassessed. Inaddition, we have used the present ICSs in a Monte Carlosimulation for modelling the behaviour of an electron swarm inthe bulk of a low current N2 discharge. The macroscopictransport parameters determined from this simulation arecompared against those measured from independent swarm-basedexperiments and the self-consistency of our ICSs evaluated.
