Absolute total cross sections for electron-impact double ionization of Kr4+. The uncertainties are relative only at the one-standard-deviation level. The total uncertainty is ±8% at a high confidence level corresponding to 90% confidence for the relative uncertainties for a typical point near the peak of the cross section. Reference: M. S. Pindzola et al., Phys. Rev. A 29, 1749 (1984).
