Single ionization cross sections for U10+ ions. Cross section uncertainties are relative only at the equivalent of one standard deviation for statistics; collision energy uncertainties range from ±0.2 (at low energies) to ±1 eV (at high energies). Absolute uncertainty for a point near the peak cross section is ±8% at the two-standard-deviation level. Reference: D.C. Gregory et al., Phys. Rev. A 41, 106 (1990).
