摘要：

Large angle scattering data over the range 15 <= s <= 60 angstrom(-1) (s = (4 pi/lambda) sin1/2 theta) for the total differential cross section for 40 keV electrons scattered by N-2 have been obtained. Comparison of this data with the simple Born and Bethe theories show that binding effects vanish by s = 25 angstrom(-1) and that these simple theories adequately represent the data to within 0.5% on an s(4)I( s) scale between 25 <= s <= 40 angstrom(-1). In the region 40 <= s <= 60 the data deviates from these theories but can be brought into excellent agreement by the use of a reasonable energy response function for the detector.
