A measurement of the cross section for K-shell ionization by 10- and 20-MeV electrons in Mg and Al has been made. These results, together with previous measurements at 50 MeV by Hoffmann et al. and at 70 and 230 MeV by Kamiya et al., allow the increase of the cross section with energy to be defined. The results are found to support the claim of a density effect by Kamiya et al., although the extent of the saturation is not as pronounced as first believed.
