N+ charge transfer in N-2 at low-keV collisions

The absolute differential and total cross-sections for single electron capture at energies between 0.5 and 5.0 keV are reported. The reduced differential cross-sections shows an overall increase of at least one order of magnitude and a monotonic decreasing behavior at all the collision energies studied in this work. The total cross-sections for single electron capture are compared with previous experimental measurements. The total cross-section results presented in this paper and obtained by integration of the measured differential cross-sections agree with previous measurements using a beam of pure ground state ions.
