Formation of O2+ in collisions between O+ ions and N2 molecules

We report measurements of the total and absolute differential electron loss cross sections of 2.0-5.0 keV O+ ions in collisions by N2 target at scattering angles between −3.2°≤Θ≤3.2° in the laboratory frame. The behavior of the absolute differential cross sections display an expected decreasing behavior with increasing angle. The measured total electron loss cross section show a monotonically increasing behavior as a function of the incident kinetic energy and found to be within the order of magnitude between 10−19 and 10−21  cm2.
