We present tables of the excitation cross-sections from the ground and some lower excited states and corresponding collision strengths for electron impact excitation of nitrogen ions of all degrees of ionization for an energy range from threshold up to 50 times the threshold energy for direct transitions, and for exchange transitions up to 12 times the threshold energy. Coefficients of the standard analytic approximation of the collision strengths, valid for direct transitions up to 100 times the threshold energy, are also given.The calculations are made using Coulomb-Born-Exchange approximation. |
