Electron-impact double ionization cross sections for U10+. Uncertainties listed are relative combining one standard deviation on counting statistics with uncertainties in the form factor. Total uncertainties are approximately ±10% at a 90% confidence level for a typical point near the peak cross section. Note that the cross section is listed in units of 10-19 cm2. Reference: D.C. Gregory et al., Phys. Rev. A 41, 106 (1990).
