Absolute Total Single–Electron–Capture Cross Sections of O2+ with N2 Gas

Abstract

Abstract: Absolute total single-electron-capture cross sections have been measured for lowenergy O2+ + N2 system in the collision energy range between 0.50 to 2.0 keV. These cross sections are found to be in the range of 0.67 to 2.08 x10-16 cm2. The measured total cross sections for single-electron- capture display a slowly increasing behavior as a function of the incident energy. Several measurements of total cross sections for electron-capture from N2 by slow N2+ and O+ ions, and from O2 by slow O2+ ions presently exist in the literature. In the measurements reported here, we measured the total cross sections for electron-capture from N2 by slow O2+ ions, such measurements are not found in the literature. The increasing availability of data on this system may stimulate work in this direction.
