Monoergic electrons were scattered from thin foils of aluminum, nickel, silver, and gold. The scattered electrons were analyzed by a 90 deg magnetic spectrometer using a scintillation detector. The absolute cross sections were measured at 30 deg with an estimated error of 3%, at 60 deg and 90 deg with an estimated error of 2%, and at 120 deg and 150 deg with an estimated error of 5%. The experimental results were 5 to 10% lower than the values predicted by the Mott theory as evaluated by Doggett and Spencer. When tbe theory is corrected for the effect of nuclear size and the radiative correction of Schwinger an improved fit results. However, the discrepancy between the corrected Mott theory and the measured cross sections is well outside the experimental error. (auth)
