Abstract
A new absolute measurement of the cross section for the process Ne++e to Ne2++2e has been made at electron energies from threshold to 2 keV using the crossed electron and ion beams technique. The total error at a 90% confidence level is estimated to be +or-5%, increasing to +or-7% at energies greater than about 1 keV. The present cross section is about 6% greater than that measured by Dolder et al. (1963) near the peak, increasing to 11% at higher energies. The cross section of Muller et al. (1980) has the same shape as the present data from threshold to 400 eV, but is about 20% lower in magnitude. Above this energy it falls more rapidly with increasing energy and is more than 30% lower at 800 eV. The recent measurement of Achenbach et al. (1984) is in excellent agreement with the present data.Keywords
