Abstract
Cross sections are reported for the production of fast negative fluorine ions in collisions between a neutral fluorine beam and single atoms of each of the rare gases, at collision energies between 20 and 110 keV. The energies at which the cross sections pass through a maximum fit very well with the Massey criterion, assuming a simple electron-transfer theory. The cross sections for the production of fast fluorine positive ions are also reported. These are found to be smallest for the heavy targets and reach a maximum in helium and neon, which have higher ionization potentials than fluorine.
