We have investigated the effects of the Moller interaction in relativistic distorted-wave calculations of cross sections for electron-impact ionization of high-[ital Z] hydrogenlike ions. We found that the Moller interaction significantly increases the cross section for hydrogenlike uranium, and brings our calculated results into very good agreement with experimental results reported by Marrs, Elliott, and Knapp [Phys. Rev. Lett. [bold 72], 4082 (1994)]. We found similar increases in the cross sections for other hydrogenlike ions. Our results also show that these effects become important at much lower collision energy than previously reported [D. L. Moores and M. S. Pindzola, Phys. Rev. A [bold 41], 3603 (1990)]. With the Moller interaction included, our cross sections for these ions are in good agreement with preliminary results obtained in recent experiments on the electron-beam ion trap (EBIT).
