R-matrix calculation of integral and differential cross sections for low-energy electron-impact excitations of the N-2 molecule
These excitations, especially of the higher four states, have not been studied enough theoretically in the previous literature, and good agreements are observed both in the integrated and differential cross sections, especially around a peak structure.

Spatial Distribution of Excited Molecules Induced by Proton Beam in Nitrogen Gas
Spatial intensity distributions of spectral bands are obtained by 100 and 150 keV proton impact on molecular nitrogen gas target. All bands of the N 2 second positive system
Anisotropic scattering of electrons by N2 and its effect on electron transport.
The changes in the commonly measured transport and reaction coefficients resulting from the introduction of anisotropic elastic and inelastic scattering, while keeping the elastic momentum-transfer cross section constant, are less than 1%.
Integral cross sections of the dipole‐allowed excitations of nitrogen molecule studied by the fast electron scattering
The integral cross sections (ICSs) of the electron scattering of nitrogen molecule are of great importance to the understanding of many different aspects of atmospheric physics. In the present work,
