Measured cross sections for single ionization of Si3+ 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 ±12% at 90% confidence level. Reference: D. H. Crandall et al., Phys. Rev. A 25, 143 (1982).
