AB: Integral cross sections for electron impact excitation out of the ground state (X ¹σ_g⁺) to the A ³σ_u⁺, B ³Π_g, W ³Δ_u, B' ³ σ_u^-, a' ¹σ_u^-, a ¹Π_g, w ¹Δ_u, and C ³Π_u 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 ¹Π_g 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 ¹Π_g → X ¹σ_g⁺). The present results are compared and critically evaluated against existing cross sections.
