In this Reply, we demonstrate that at large momentum transfer (|q| = 2 a.u.), within the experimentally accessible angular range of the ionized electrons, there is good agreement between experiment and the first Born calculation concerning the shape of the cross section. Furthermore, we show that the fact that our results for (e,3e) double ionization seemingly "contradict well-accepted results in (e,2e) single ionization" can be traced to a second Born process in which the projectile interacts with both target electrons in sequence. This process competes effectively with other double ionization mechanisms but is relatively unimportant for single ionization.
