Figure 4

Total ionization cross sections for Ne*(3P2,0)-N2 as a function of the collision energy. (a) The full circles are results from the Perugia laboratory29. Marked red and black lines indicate the calculations of the present study carried out within the semiclassical approach6,7 and according to Eq. (3). (b) thin-pink and thin-black lines represent polynomial functions interpolating data measured in the Eindhoven laboratory18. Vertical error bars are representative of the uncertainties on the absolute scale of cross sections. Full lines are the same of (a) panel. (c) the contribution from each entrance channel leading to the formation of N2+ in its ground 2Σg+ electronic state.
