Dielectronic-Recombination Cross-Section Measurements forC+Ions

Abstract
With use of a merged electron-ion beam apparatus, a lower limit of dielectronic recombination cross section for C+(P2)+e has been obtained from 9.04 to 9.32 eV. The measured cross section exceeds the theoretically predicted value by more than a factor of 3. This lies well outside the stated experimental and theoretical uncertainties.
