Measured cross sections for single ionization of Ta3+ by electron impact. Uncertainties are one standard deviation counting statistics only and taken as representative of relative uncertainties. Total uncertainty for a typical point near the peak cross section is ±18% at 90% confidence level. Reference: R. A. Falk et al., Phys. Rev. A 27, 762 (1983).
