Integral cross sections for the electron impact excitation of the X ^{1}Σg+(v=0) level to the b, c, and o 1Πu Rydberg-valence series of N2 are reported at incident energies between 17.5eV and 100eV. These cross sections are obtained by integrating recently obtained differential cross-sections taken for N2 in a similar way as in [1, 2], i.e., from unfolding N2 electron energy loss spectra taken at electron scattering angles between 5° and 130°. However, in this case adiabatic perturbations between these Rydberg-valence series were taken into account. The present results are compared to existing cross sections.
