The absolute differential cross-section for charge transfer scattering of 1.5 keV protons with atomic oxygen

Abstract

The absolute cross section, differential in laboratory scattering angle, for the process \rm H\sp{+} + O\to H + O\sp{+} using 1.5 keV-energy protons is reported. The total cross section value of (8.7 $\pm$ 1.9) $\times$ 10\sp{-16} cm\sp2 derived from the integration of the differential cross section is compared with existing cross section data
