    Notes: Abstract Measurements of the elastic small-angle scattering cross sections of silver for 60 keV electrons having been performed with silver-atom beams are communicated. The results agree with the theoretical values ofIbers andVainshtein. Comparison of the experimental results with the earlier measurements of the cross sections made with silver films shows no agreement at all. So the conjecture of several authors that the great differences between the theoretical small-angle scattering cross sections and those measured in foils are due to differences of the cross sections between isolated and condensed atoms could be verified.

    Notes: Abstract The cross sections ofIbers andVainshtein are the current basis for the discussion of the small-angle scattering of electrons. As these cross sections have been calculated in the first Born approximation the limits of their validity are but roughly known. By absolute measurements of the cross sections for Ar, Kr, and Xe at 37, 60, and 100 keV between 5 and 65 mrad the range in which the Ibers and Vainshtein values are no longer valid was determined. The agreement with these values was good for Ar at all energies and for Kr at 60 and 100 keV. In the other cases deviations have been found which increase with increasing angle and atomic number and decreasing energy. Similar results have been found by measurement of the cross sections for inelastic scattering and comparison with the corresponding theoretical results ofFreeman andWatson.
