Electron-impact single ionization cross sections for Cr6+. Uncertainties are typical relative uncertainties, which combine one standard deviation on counting statistics with uncertainties in the form factor. Total uncertainty for a typical point near the peak cross section is ±9% at 90% confidence level. Reference: M. Sataka et al., Phys. Rev. A 39, 2397 (1989).
