Abstract
Cross sections for the formation of Mg2+ by collisions between protons and Mg+ have been measured at barycentric energies between 0.98 and 44.5 keV. For energies between 3 and 20 keV the cross section is approximately constant at 7*10-16 cm2 although some small structure can be resolved. Below 20 keV there is remarkably close agreement between these measurements and the earlier calculation by Bates et al. (1964) for the process Mg2++H to Mg++H+. Evidence is presented to indicate that impact ionisation of Mg+ is insignificant below 20 keV and so the measurements are believed to refer almost exclusively to the near-resonant charge exchange between protons and Mg+.Keywords
