Calculations of differential cross sections of (e, 2e) reactions on Cu and Ag atoms in the eikonal approximation are described for ( e, 2e) experiments that have recently been carried out in Tiibingen. It is shown that even for highenergy impinging particles the angular profile of the differential scattering cross section is sensitive to the magnitude of the mean intraatomic field. This suggests the idea of using the angular shift of the maximum of the differential scattering cross section in symmetric (e, 2e) experiments for direct determination of the mean intraatomic field.
