Measured cross sections for single ionization of Cl2+ by electron impact. Uncertainties are one standard deviation from counting statistics and are taken as representative of relative uncertainties. Total uncertainty for a typical point near the peak cross section is ±8% at 90% confidence level. Reference: D. W. Mueller et al., Phys. Rev. A 31, 2905 (1985).
