Integral cross sections for electron impact excitation out of the ground state (X 1σg+) to the A 3σu+, B 3Πg, W 3Δu, B' 3 σu-, a' 1σu-, a 1Πg, w 1Δu, and C 3Πu states in N2 are reported at incident energies ranging between 10 and 100 eV. These data have been derived by integrating differential cross sections previously reported by this group [Khakoo et al., PRA, 71, 062703, 2005]. New differential cross section measurements for the a 1Πg state at 200 eV are also presented to extend the range of the reported integral cross sections for this state, which is responsible for the emissions of the Lyman- Birge- Hopfield (LBH) band system (a 1Πg → X 1σg+). The present results are compared and critically evaluated against existing cross sections.
