Abstract Electron-impact double ionization of magnesium has been observed in an {ital e},(3{minus}1){ital e} experiment. A 1.0-keV incident electron is used and two 100-eV ejected electrons are observed in coincidence. The scattered electron is not detected so that the cross section is integrated over all values of momentum transfer. A preference is observed for both target electrons to be ejected in the forward direction. In contrast to single ionization in the same energy regime, it is found that from 1 to more than 5 a.u.of momentum may be imparted to the ion core in the doubly ionizing collision. {copyright} {ital 1996 The American Physical Society.}
