Absolute differential and total cross sections for charge transfer of O+ ground and mixed states ions in N2

Abstract

We report measurements of the total and absolute differential cross sections for charge transfer of ground- and excited-states O+ ions at 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5 and 5 keV in collisions with N2 at scattering angles −5.2° ⩽ Θ ⩽ +5.2° in the laboratory frame. Total cross sections for ground- and mixed state ions are compared with previous measurements. The behaviour of the absolute differential cross sections display an expected decreasing behaviour with increasing angle. The mixed state ions cross sections are considerably higher than those measured for the ground state ions.
